We are fellow users here on these user-to-user forums, we won't know. Did you have any pre-orders or auto-renewing subscriptions due ? Have you checked your account's purchase history : http://support.apple.com/kb/HT2727 ? If you can't see where it went (and you've tried logging out and back in again) then try contacting iTunes Support and see if they can help : http://www.apple.com/support/itunes/contact/

When downloading updates for Quicktime 7 and Itunes 10 I keep getting an error saying that files shared by these updates has an invalid signature and that the downloaded has been removed.

When downloading updated for Quicktime 7 and Itunes 10 I keep getting an error saying that files shared by these updates has an invalid signature and that the downloaded has been removed. If I don't get that message I get a message saying that the download was unsuccesful and that in order to download I need to go to tools and then select dowload only. Please help I really want to update my iphone!

Thanks for helping out, but I already tried these steps.
I even tried this on a iMac with similar results. The only difference was that the errorcode was called 2001 instead of 21.
Today I took the phone to www.iphoneambulancen.dk. A guy (in Aarhus, Denmark) that specializes in iPhone repairs. I figured, that given his occupation he'd seen most errorcdes. Two hours later, he called me back, and told me that he had replaced the battery.
So, it turns out that a broken battery can cause this behaviour.
But thanks again

I deal with a itunes update problem when i try to update i get coneection has timed out error! i had the same problem when i had vista.. yesterday i formated my pc but i still have the same prommblem. i dont deal with such problems on direct downloads.

Sorry I gave this a 'this helped me' but after a long struggle I found some ticked box somewhere from some unauthorised chrome extension blaaa....... the link you gave was great, not only did it confirm all the bad things google is supposed to be up to it provided a better browser. Cheers man.
Anyone who find this; I disabled all extension in chrome. I then searched the word proxy in the settings section. A button came up, "change proxy settings" I clicked on it. Earlier it was greyed out as an extension was interefering.. It brought up a box with my own settings from my computer. Then I clicked LAN settings, then unchecked the 'Use a proxy server' button.
P.S. If you're using chrome, bail, and dowload Komodo Dragon. It's virtually identical, but you're not tracked, and you can use chrome extensions, and you can quickily transfer your chrome preferences into it.

When updating iTunes I get a message saying invalid signature and it won't update, is there a fix for this?

When updating iTunes on my PC I get a message saying "invalid signature" and it won't update. Is there a fix for this that I can do myself or do I need to take it in to a computer guy?

What kind of things are you seeing as disabled?

If you have the latest version of iTunes you should not have to download the ipsw file separately as jalp suggests. iTunes will download it automatically.
This error (9) most often means that your antivirus or firewall (or router) is blocking access to Apple's servers. In rare instances it can also mean that the phone was hacked (or "jailbroken") to unlock it. If this is the case you must do a DFU restore, not Recovery Mode, as follows:
Reboot your computer
Disable your antivirus and firewall. If you has Kaspersky you may actually have to uninstall it, as it can never be turned completely off.
Connect the USB cable to a USB port directly on your computer, not to a hub. DO NOT connect the other end to the phone
Disconnect all USB devices except for mouse, keyboard and iPhone cable.
Launch iTunes
On the phone hold the HOME and SLEEP buttons at the same time for EXACTLY 10 seconds, then release the SLEEP button but continue holding the HOME button. The screen should be black. If it has an Apple logo this means you held both buttons too long. Release the HOME button and do it again.
While holding the HOME button connect the free end of the cable to the phone.
After a short while iTunes should recognize a phone in "recovery mode" (iTunes doesn't know the difference between DFU and Recovery modes, but the phone does)
Release the HOME button and don't touch the phone or the computer until the process completes or you get an error message. Ignore any displays on the phone.
If the error recurs the phone was probably messed up when it was hacked. This is not a hardware problem, or if it is, it isn't one you can fix.
You can try repeating these steps with a different computer and a different cable. If that fails also the phone is probably not repairable.

TS2446 Ipod touch displays "Your Apple ID has been disabled" when attempting to update Apps.

How do I work through "Your Apple ID has been disabled" on an Ipod Touch?
My child's Ipod touch displays "Your Apple ID has been disabled" when attempting to update game Apps. I have reset the password, and reset the Ipod to factory settings; did not resolve. This began by entering wrong Apple ID password multiple times. Thank you.

HT1218 After a recent iTunes update attempt iTunes no longer functions and the airport extreme base station is not accessable on our computer. We still have wifi but cannot access the base station software.

After a recent iTunes update attempt iTunes no longer functions and the airport extreme base station is not accessable on our computer. We still have wifi but cannot access the base station software.

Thanks for the reply. I appreciate the response. I tried that approach this evening and it didn't work for me. (Technically it worked for me, when I was hardwired into my base station, but would not work for me wirelessly, which is my main issue.)
Again, using the approach you recommended works only if I have my ethernet cable attached to the LAN port so my computer is communicating directly to the base station through the hard wire. I am able to scan for my base station and make setting adjustments normally this way too.
As soon as I disconnect from the LAN port and try to go wireless is where I run into problems. The Base Station's wireless network I created is available to choose in the top right corner of the monitor with all of the other available wireless devices/networks -- but the network I created does not have access to the internet. I am also unable to configure my Base Station wirelessly. When my Airport Utility tries to scan for the Base Station and Network, it cannot find any Apple Wireless Device. It's like the Wireless Network in my base station is not sending out a signal.
Is there a way to resolve this issue?

All my purchases in iTunes has been made by Apple ID Balance (redeem from gifcards). My account has $ 27,45 but I cannot pay any new app or even update my apps because is asked to check my credit card. I´ve have never used it to purchase my app. How can I pay any new app with my Redeem as usual? Can you help me ?

It is a Remote Desktop Client Update 3.7.1
Thank you for answering. I apologize it has taken me so long to get back in here.
I just realized that I wrote that I installed from app store originally, but I must correct that statement. I never paid for the app so it must have come preinstalled on my 2011 iMac. I was confused since the update is through the store so I assumed I downloaded it. Sorry for any miscommunication.
So to be clear, even though I have never remotely administered / accessed my computer and I no longer have ARD on my computer, it is normal to have the client update appear in my App Store. Is that correct?
I appreciate your assistance.
