Ok last night after I posted..... I tried the search again and it worked .... just now I opened the limewire again and the search worked again... I think it might be the servers for peer to peer work.... it might do it to some....and not others ... ok ...if you want to try what I did in case that fixed the problem.... you have to unistall the program ...then find the folder for limewire ....(it leaves a folder after you uninstall it) dont delete you exe file for limewire you used to install it... delete that folder ... then if you feel comfortable to deal with the registry, go the the registry , use the seach , put limewire in .. you should find one folder on the tree and then another file... delete those but nothing else.
Then use your exe file for limewire and install it completely new.... then if it doesnt work... leave it on for an hour and see if the search works.... if you dont understand the deleting process let me know.
