I was in Lightroom and had a power surge and now Lightroom will not launch....what can I do to fix it?

I was in Lightroom and had a power surge and now Lightroom will not launch. It encountered an error when reading from its preview cache and needs to quit. Lightroom will attempt to fix the next time it launches. I have shut my system down and Lightroom still will not launch. Does anyone have any suggestions?

delete your preview cache (.lrdata folder).
Here has location:
Preference and other file locations in Lightroom 5
If not enough info, search this forum for "delete preview cache".

After installing Cooliris and moving icon from Tab Mix Plus Cooliris will not "launch" ; how can I rectify this problem?

On another computer was causing FF to run sporadic , I believe. I have now installed on a Mac but icon is in b&w and will not launch when clicked.

If it's slow on startup it would be extensions loading or LaunchDaemons starting up.
You should have a look in:
/Library/LaunchDaemons
/Library/Extensions
You can count out anything in your home folder and it shouldn't put anything in /System as that's reserved for Apple.

Hello Vicarage00,
It sounds like the app on your iPad is quitting unexpectedly. I recommend following the steps in the article below for an issue like this (you can skip the step to download another app from the App Store since it is not related to this issue):

i really dont know much about the new ipod my husband bought me i would really like some help i had to download a new itunes and everything just to connect it im so confused please someone help

You should really read the manual.
"How do you restore from backup? "
Restore. When given the choice, choose to use backup.
"And how can I check to see if the pics and videos are on my computer somewhere first??"
They would only be where you put them. What program did you use to import them? Pics/vids taken with ipod are not part of the sync process at all. You should be importing them just as you would with any digital camera.
If you did not import them, then they are not on your computer.

I think I, by mistake, hit never alow when firefox was trying to load someting,now firefox will not install. what can I do?

Firefox needs to update. When I try to install the bar just keeps going and going for hours. I think a plug in or something that I did not recognize wanted access and for the first time I hit never allow. I have tried to disable my McAfee firewall and that did not help. Is there anything that I can do at this time to install update?

If you have problems with updating then best is to download the full version and uninstall the currently installed version.<br />
You may need to remove the Firefox program folder to do a clean install of the new version.
Download a fresh Firefox copy and save the file to the desktop.
* Firefox 4.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Do not remove personal data if you uninstall the current version.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder] and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Has there been trouble with the charger. I am getting to re-order but the one i had the had the power surge and the end was blackened. Not sure if it safe to use the laptop again?

Has there been any trouble with the charger? I am getting ready to re-order but the one i had.... the had the power surge and the end was blackened. Not sure if it safe to use the laptop again? Thanks.

Can you also see blackening in the power jack on the PowerBook? If so, I would be worried that the surge also damaged the computer/
Does the computer run OK on just the battery? If it is working on battery power, that limits the number of things inside the computer that could have been fried.
If the computer is severely damaged by the surge, it's not worth repairing. However, a couple of posters in Apple forums said their homeowners'/renters' insurance paid them replacement value of their computer after power surge damage due to known problems on the grid, like the huge power outage that hit the SW Untied Stats and part of Mexico yesterday.

I suspect unless he had some items in iCloud backup then they are gone. Connecting an iPhone to a different library from that to which it was previously connected will result in the device asking if you want to erase it.

TS2811 After updating to ios 6 my phone had to be restored. Now it will not acitvate. I am receiving the message that ther server is unavailable. However, I can not use my phone at all until it is activated. why can I not activate?

After updating to ios 6 my phone had to be restored. Now it will not acitvate. I am receiving the message that ther server is unavailable. However, I can not use my phone at all until it is activated. why can I not activate?

Well, 99.9% of the time, the cause of this issue is the fact the phone was jailbroken/hacked to unlock it for use on networks other than the network the phone was originally locked to. Apple maintains a database of officially unlocked iPhones, and when Apple's servers detect phones such as yours, activation stops & you get the message you got.
So, either get a sim card from the carrier your phone was originally locked to, or get it officially unlocked.

Hello, Jdragone.
Thanks for the question. Start with completely uninstalling iTunes and all of it's components in the order specified in the article below. Once this is done, download and install iTunes.

Did you try to reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again? You will not lose data by resetting, but it can clear some glitches.
If this does not work, try to set it up as new device without using the latest backup.

SW upgrade wiped out my iTunes library and also now iTunes will not launch

I just completed the recommended Sw upgrade for iTunes and now iTunes will not launch and my iTunes library is TOTALLY EMPTY.
Clearly, I am NOT A HAPPY CAMPER. I have lost a substantial investment of $$ and time in losing my iTunes library - so Apple should be paying me for my loss.
I need help, can you, will you help me? I want my iTunes library back and I'd like to reinstall the previous version of iTunes, because it worked fine.

You don't say which versions so we don't know to which version you wish to revert. Reverting won't get back your library anyway, if it is truly gone.
Have you checked if your library is truly gone? Have you looked in the iTunes folder and the media folder inside of it? The library has two main components, all the media files for the individual tracks and the iTunes Library.itl file which give them the structure you see in iTunes. Sometimes iTunes just loses track of the library file which can be re-linked, and what's really important anyway are the media files.
If the library is truly gone you can restore it from the backups you make of your computer. Backups are a responsibility of any computer owner ever since computers were invented. If you don't have backups then it may be possible to redownload items purchased from the iTunes Store.
I know I have glossed over some of this but it's not worth going into details on how to do all the different things until we know precisely what it is that needs doing.
