Library is locked?
 

I restarted my computer this morning and when I opened Limewire, I got a message saying a folder has been locked by another program. The only folder I cannot access ( hell, it's not even listed anymore) is my completed folder in my library. I still have the incomplete folder though. I downloaded another song, and it downloaded fine, then when it was complete it disappeared. Has this ever happened to any of you, and where do I begin to try to unlock it? Please help, this is driving me crazy.....
