How to get songs back in shared files for Limewire?

[megaecurious]

I went to turn my laptop (Dell) back on found something on the bottom coming off (has a little battery sign on it, so Im guessing the battery), so I pushed it back on and when my laptop fired back up, all my songs on Limewire were gone. Everything in shared files...GONE. And now none of my songs in my i-tunes are working and are coming up with the little (!) sign.

Somone PLEASE tell me if I can get them back without downlaoding all my songs again. PLEASE HELP!!!
