Songs lost in headache box

[Babs]

Ok, I downloaded itunes cause we use it at work and thought I would give it a try. I moved songs around using <Start / Explore> and when I went to Limewire all my songs were gone. I did a system restore didn't fix the problem. I went and moved songs back from my music to the limewire shared folder and now all that is there is my folders, but no songs in them. Help, please, I don't want to have to download everything again. I know they are in my computer somewhere cause I still have them in my windows media player. Thanks, Babs
