Unknown error (-50) occurs upon startup after upgrade to iTunes 7.0.2

I just let AutoUpdate upgrade iTunes to version 7.0.2 (along with the iChat upgrade and last two security fixes), and after restarting my computer, I can no longer open the iTunes. Upon clicking the dock icon, I am asked to agree/disagree with the iTunes Software License Agreement (so I agree), and then get the error: "The iTunes application could not be opened. An unknown error occurred (-50)." I tried repairing permissions, which apparently found some discrepancies with files associated with iTunes, but it did nothing to solve the problem. What should I do?? Would downgrading to iTunes 7 fix it? (I don't remember whether I had ever made the upgrade to 7.0.1).
Thanks,
Jenna

Ended up moving the whole iTunes library and plists to another folder and starting iTunes, then copying the iTunes music library and xml back into the folder to replace the newly created ones. Seems to be working and the play counts/playlists are intact. In case anyone else happens to have a similar error...

Brand New iPod- Brand New Account- Could Not Sign In An Unknown Error Has Occurred

Just got home with a brand new iPod touch from the Apple Store. iOs 6.0.1
Set up a brand new Apple ID and iCloud account. Verfied and confirmed the account via email on the iPod. iPod has not been attached to a computer.
I am attempting to download some free apps from the App Store and I get the following error:
Could Not Sign In An unknown error has occurred.
I went into Settings/iTunes & App Store and attempted to enter my Apple ID and Password. I get the same error:
Could Not Sign In An unknown error has occurred.
I clicked on Forgot Apple ID or Password? I then select Enter Your Apple ID. I go through the Password Retrieval process in iForgot. I select Answer Security Questions. I verify my date of birth. I correctly answer my Security Question. I attempt to enter the same password I already have (in an attempt to eliminate the scenario where my password may have been mistyped). I get the following message:
The password specified has been used in the past year. Please select another.
Now I know that the password I have been entering in the App Store and in Settings is correct becasue I just set up the new account and have only had one password.
I cancel out and close the Safari iForgot window.
I go back to the App Store and attempt to login using my correct Apple ID and an intentionally mistyped password. I get the following message:
Your Apple ID or password is incorrect.
Now I know the Apple Store does indeed recognize my correct Apple ID/Password combo, otherwise I would get the same Unknown Error message.
I have attempted to force quit all apps, reboot, re-try and reboot ad nauseum, but to no avail.
So, someone at Apple, tell me, what the heck is going on? How do I proceed?

I've just found the fix!!!!!! I downloaded itunes to my home PC and logged in using my newly created account, a message came up saying that i've not used this account yet with itunes and I need to confirm settings. It basically took me through my credit card information and personal details (strangely it wanted my title as a required field, yet on the ipad setup it didn't - maybe check this field is filled out in your account settings). Then it gave me a message saying I was ready to use the account. I logged into my ipad and all was good - literally did it 2 seconds after seeing the message on my PC. I hope this helps you also ;-)

Hi apiccolo5,
Thanks for visiting Apple Support Communities.
See these articles for steps that can help you resolve the issue you're seeing:
iOS: Unable to update or restore
http://support.apple.com/kb/ht1808
iTunes: Specific update-and-restore error messages and advanced troubleshooting
http://support.apple.com/kb/TS3694
Error 20, 21, 23, 26, 28, 29, 34, 36, 37, 40
These errors typically occur when security software interferes with the restore and update process. Follow Troubleshooting security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service.
Also, check your hosts file to verify that it's not blocking iTunes from communicating with the update server. See iTunes: Advanced iTunes Store troubleshooting—follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > Mac OS X > The hosts file may also be blocking the iTunes Store. If you have software used to perform unauthorized modifications to the iOS device, uninstall this software prior to editing the hosts file to prevent that software from automatically modifying the hosts file again on restart.
Best,
Jeremy

Getting "Unknown Error has Occurred" After Project Server 2013 DB Restore

Hi All,
I have restored our content and pwa databases as per Microsoft's guide, one Project Web App works fine and the other has the error "An Unknown Error has Occurred" on the projects view and also when viewing Enterprise Project Types.
Another thing I have noticed is that only the Sys Admin has access to the project sites even though users have been added as admins etc.
We are patched to the December 2013 CU / Hotfix and I have also run the provided service scripts by Microsoft to go with the hotfix.
Any help on this would be greatly appreciated as we are looking to test SP1 and apply to our production environment.
Thanks in advance...

PowerShell has a command called. Test-SPContentDB.
Run the TEST-SPContentDB powershell command on database and see if it provides additional information.
Cheers

How to fix 'An Unknown error has occurred" when trying to save an illustrator CS5 doc

Hi
I have just upgraded to a new iMac late 2013. After running a migration from my old mac to the new. I now have the following error: "Unknown error has occurred" when trying to save an illustrator CS5 doc.
How do you fix 'An Unknown error has occurred" when trying to save?
All help, most welcome.
Thanks
Marty

There was a problem downloading ... An unknown error has occured -42018...

Dear all,
After upgrading to i-tunes 7 I'm not able anymore to download music. If I run diagnostics everything seems fine.

However downloading the songs I bought doesn't work.
Following error:
"There was a problem downloading "...". An unknown error has occured (-42018). Please check that the connection to the network is active and try again."
But my network is active and the diagnostics turn out OK. Please help me out!! I have songs to be downloaded that I have already payed for.

This didn't work for me, but to any who may be interested, I also was experiencing unknown error -42018 when attempting to download purchased music. Additionally, I was stuck in an endless authorization loop when attempting to play previously purchaed music. All this started when I installed the latest iTunes software 7.0.2. But I managed to fix the problem on my machine.
I run windows XP Pro, and unlike the majority of users I actually set it up correctly with a dedicated administrator account, and regular user accounts instead of just running as admin all the time. For me, that was the cause of the problem.
The new version of iTunes software required FULL CONTROL privilages on the iTunes and iPod install directories for all user accounts that were using the program. (Previous versions worked fine, so this is a new thing.) Once I provided those permissions, iTunes worked correctly. Follow this link: http://support.microsoft.com/kb/304040 for information on how to provide FULL CONTROL to every user account.
I hope you all find this helpful in solving your problem.
Good Luck,
Bill

CS3 when saving message "an unknown error has occurred"

In illustrator CS3 when trying to saving the message "an unknown error has occurred" pops up. The only way I can get a file to save is saving it as an template. I've tried reinstalling and removing the preferences. Any help would be appreciated.
Thanks

AArrrrrrrggghhh!!!!!!! phew.. sorry.
I have the same problem and I have come to a schtuck. The problem began out of the blue in my illustrator CS2 which was working fine before, so I upgraded to CS3, and the problem is still there, I have tried removing the preferences, I have uninstalled all versions of illustrator including preferences from the PC and reinstalled only CS3 brand new straight out the box. Still won't save.
Any ideas anyone?
I think it's ridiculous that we have paid £2000 for the New CS3 master collection and it doesn't work properly! how can adobe release software with a problem so big as this and charge so much for it? My boss rang adobe yesterday to ask for help and after a long while of not getting anywhere the adobe guy he was speaking to said 'I've had enough of you' and hung up the phone!!! What is that all about? we are legitimate paying customers of adobe for the last 10 years or more! I have now missed a big deadline because of this and am in a mind to asassinate someone at adobe! hahahaha.
Sorry to rant guys but come on adobe! sort it out!
Anyway,
If ANYONE has an aswer or an idea of how I can fix this problem and get back to work I would be very grateful.
some info about my project incase it helps:
I am using CS3 master collection freshly installed on a Dell precision 650 PC with intel xeron processor, XP operating system, 37.6GB free hard disk space, 2 Megs of ram, Nivida Graphics card.
My Illustrator project is a 0.5x2 metre banner made up of a large number of collaged Hi resolution JPEG photographic images. The only composition I have used is Opacity masks with feather effects.
There is no text in the project and no other elements apart from the masked and feathered images.
the original images are stored on an external hard drive with loads of free space on it.
Any ideas I would be very grateful, as I said I have already tried deleting the illustrator settings and preferences files, and re-installed CS3 to no avail.
Thanks! Beth

An unknown error has occurred when trying to sign in , and I know I putting in the correct info, this stinks can anyone help? Because apple isn't...

urgh... just noticed my previous post said i have mountain lion... i meant that i have snow leopard. no idea why i messed that up!
anyway, i just tried reinstalling snow leopard from the usb key that came with the computer. Then, I installed software updates until it told me there were no more updates. After that, I tried the app store again, and it still is giving me the unknown error. really irked by that. may have to take it back to the apple store yet again, to see if i can figure out why the app store won't work.

I can't connect with the App store. It says "An unknown error has occurred"

This just started a few days ago on my MacBook Pro. My account is working fine - I can access it on my phone. But I can't get to it on my computer.
The first sign of trouble was when I tried to use a previously purchase app. The app wouldn't open and gave me a message saying it wasn't purchased on this computer (which it was) and that I needed to enter my password. When I entered it, it said "An unknown error has occured". The first time it happened, I rebooted the machine and then the app opened and I was fine. Next day same problem. Our IT guy (not a real IT guy, I work for a small company and he is the most knowledgable about computer so he gets to do double duty) suggested making sure all software was up to date. I downloaded updates, the computer rebooted, and I was fine again. Day three comes and same problem. Rebooting didn't help. IT guy suggests upgrading to latest OS. But when I try to access the app store to get the new OS, it asks for my password, and then says "An unknown error has occurred". The computer can see my account. It has my ID right, and I have a credit balance which I just updated last night and is being properly reflected on the home page. But I can't buy anything or see details about my account. I keep getting the same pop-up.
Any idea what is happening or how to fix this?

On what OS?

I was installing a new update on my MacBook Pro. With only 20% left it said "an unknown error had occured, please restart your computer." Now that I've restarted - I can't log in!

Ok, my MacBook haven't had any issues earlier, until today. At first Safari was acting kind of weird in that sense that a lot of letters were missing when you went on certain webpages, so I thought of updating since an alert-window popped up and notified that new updates were ready to be installed. So I opened up App Store through my Applications-folder and selected update.
First it asked if I wanted to connect my Mac to a powersource but since I had charged the battery to 79% I didn't think it was necessary. So I continued, computer restarted and began installing the updates.
Everything went fine until it was approximately three minutes left. An error message popped up and said something like "An unknown error has occured. Please restart your computer and try again". I pressed OK, rebooted my computer and when it asked for my password I typed it in. After I pressed OK, the computer indicated it was the wrong password. I tried multiple times and sometimes with different passwords... so now I can't simply log in! What's the problem?
TL;DR - Updated mac, failed after five minutes and now I can't log back in since "I have the wrong password"

Corrupted/Locked out apple ID "An Unknown Error has occurred" logging into support?

I was forced to use a different apple id to log into this support community because all attempts from different devices and browsers using another ID have ended up at the password prompt with "An unknown error has occurred" at the community login screen. The ID can still be "manged" and appears to be able to make purchases from the iTunes Store over the internet. A phone incident case number 388249960 was opened and I spent over an hour on the phone with this problem. The ID in question was set up more than two years ago to help with my wife's iPad 1 which we paid 800 plus for,,, all the storage and bells and whistles. Recently she started using the iTunes store to purchase and download television series and we got in trouble because her directories were filling the c:drive on a Vista Business computer she normally uses. Before starting to deal with the problem of storage, I tried to make sure everything was up to date and downloaded/installed the latest iTunes 11.0,1,, to her machine. I already had it on another machine running Windows 7 and two older Windows XP machines. All of them were "tested" for home networking to our Apple TV so that I could go to the TV and find a computer which could be used as a source for streaming music, videos, etc., etc. all based on her ID. As of this writing, I believe all of that functionality still exists, but, when I navigate to support and try to log in using her ID and password, I get re-prompted for the password and then "Locked Out" when "An Unknown Error Has Occurred" pops up above the login via the web site.
I am writing this after much agony and travial via an obsolete instance of Windows Explorer running on Windows XP Home Premium on an old portable using a newly created Apple ID which does not appear to have the same problems logging into the support community. Can anyone out there help me?
I have gone to war with Comcast's "free" security enhancement software "Constant Guard" believing that it might be the source. This machine had it installed at one time and has had it completely removed, but... it still experiences the error when my wife's ID is used.
The issue may be related to the recently added requirement for secuity questions and recovery email addresses which I tried to address for her ID and inadvertently ran into conflict/problem with using certain other email addresses with her ID. Perhaps something is corrupted in the database for her ID, or related to problems with support for esoteric things like Microsoft's .NET enhancements which I have long been using on my computers, or possibly Constant Guard "started" the problem because it was probably running when account security data was being updated via the Apple web site? I tried to get information about what I thought was the "recovery email address" associated with her account and was told by Apple Web sites that it was "in use" as an apple ID and could not be used as her recovery address. When I called trying to confirm that this ID was "mine" I was able to provide one of two security clearance pieces of data, but not enough information to get the support person to straighten things out for me. I ended up creating "yet another" ID just to get clear of the mess.
I made a suggestion to one of the folks I spoke with that an improvement to the functionality of apple ID's would be to support "consolidation" of accounts so that if several different Apple devices had been registered with different ID's and they all belonged to the same user(s) that a "common ID" could be created.
I'm reluctant to post apple ID's in a public support forum, and would prefer to deal with this by private email. or phone.

The iPhone "iPhone" could not be restored. An unknown error has occured (3). How do I fix this?

I had a problem with my iPhone 5 connecting to my service provider (verizon) and also to the internet just minutes after I had used the internet to browse before work this morning. I tried soft reset, hard reset, and connecting to my computer, but nothing worked to get it back to normal. I decided to do a system wipe and restore it as well, but I get that error: "The iPhone "iPhone" could not be restored. An unknown error has occured (3)." I googled that and searched for literally 7 hours without any luck. Any and all help is appreciated. Thanks!

This has just happened to me today. I have an iphone 5 on Verizon. I was using the internet on the device normally when it started. It couldn't access any online data even though it had 4 bars of service and LTE. I restarted it and it would be stuck "Searching for network". I tried wiping the phone with no luck. It gets stuck at around 99% of the firmware restore process and hangs there for about 25 minutes before itunes gives me the error described above. I tried the recover-mode restore with the same results.
I need a working phone ASAP, this is extremely frustrating!
