Go into your library. Click on Saved Files & now Explore. Do you see them? The default for saving is C:\Documents and Settings\your name\Shared.
Do a search of your computer, look for one of the file names. Your music should still be there, unless you've deleted it by mistake
If they've been deleted, you'll need a file recovery tool to try & get them back
