no music is found

Hey i just got limewire today. I use a mac. The first time i searched for an artist it worked fine...after that i can't get anything to come up...it doesn't show there is an error...the little bar goes all the way across the name of the artist but no music comes up for it...i hope that makes sense..if not i'll try to clarify. thanks!

If it's a rare artist then sometimes no results will come up. If it's not so rare then check to see how connected you are (the five bars in the bottom left-hand corner of the screen should be all green or blue).
