o-kay I'm going out on a limb here because I have absolutly no idea what happened here but my limewire "library" (1500 songs+) has dissapeared. There is nothing in it.
PLEASE HELP ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Try searching your hdd for your files(Start > Search > All Files and Folders).

It could be caused by a virus, so scan your computer. There's one that that changes all your files to zip or exe and moves them to the program folder. See this thread: Music files changing to zip or exe: some info.

Also: WARNING: Viruses on network you should be aware of!

If still no joy, post your details: System details - help us to help you

Hey Flack, this is just a shot in the dark here, but I know it's happened to others before.
Click the Library tab and find the Little Black Triangles. If your screen is black then they should be on the right hand side toward the top. Click on one of them and see if it comes back.
I only suggested this in hopes that you don't have something worse going on.
