Ok, so i was using LImewire, I wasn't paying attention and accidently deleted the files in the Shared folder in the library. I immeadeatly noticed I totally made a mistake and tried to undo it or figure out how to get them back. I have NO clue what to do. Im hoping theres still lingering on my computer somewhere. I cant even use Itunes because it cant find the original place where the songs come from. What can i Do??

Unless you're using the latest beta version, you'll need a file recovery program to try & retrieve those files. Check the thread below for some advice

A few people have had success with the Restoration program. In the meantime, use your computer as little as possible.

Good luck
