I cannot download

Hi, ok so here's my problem, i've just recently downloaded lime wire & at first it was ok, i've downloaded 4 songs & im currently d/l 2 more siles. however now when i try to download other files it doesn't work, i type in my requested search but i dont get the screen with all the possible files to download, all i get is the search cloumns on the right hand side of the page.
If any1 can tell me whats wrong or what im doing wrong that would great. thanks, tom
