Update your Java (if it needs it) & try out the beta 4.1.5 version. Sometimes the earlier versions start to struggle. The beta has solved some people's probs. See: http://www.limewire.com/english/content/beta.shtml or if you're a pro user, you'll find the beta pro version at the bottom of your personal dwnld page. I'm too happy with the beta version now to go back.
