Suddenly, search coming up empty.

Hello. This is my first post. I've used limewire for a couple of weeks, never having any problems until today. I type in the name of the artist, click on search, and it comes up empty. These are artists that I've searched before and know that there are loads of files available, but my limewire search doesn't find them. Can anyone tell me what I may have done and how to fix this? Thank you, Sue
