This is not an uncommon problem and you are in the wrong forum.
At the top of the forum you are in there are some stickies. One is this one:
http://www.gnutellaforums.com/showth...threadid=33602 Please read
From there follow the link to the Limewire Forums. Scroll down and read the forum rules and browse through the forums at the stickies at the top of each one, and see if you can find an answer to match your problem ... I'm not sure where to point you as you have not explained if it is a connection problem or a downloading problem etc. In case you do not find a solution post back, but please give us some useful information, as suggested in the forum rules, which can help us help you.
