I was just using my Limewire and, somehow, the songs I had in my library are gone. They are only in my playlist now and won't play. The message I get when I click on a song in my playlist is: "Limewire cannot play the file...the file cannot be found." I'm worried that I'll have to re-download hundreds of songs from scratch. Please tell me if there's a way to fix this. I checked under the different file folders and don't see them anywhere. Help!
