I would try reinstalling the Java Runtime Environment. You can download it <A href="http://java.sun.com/j2se/1.3/jre/">here</A> for any OS. If this is in Windows, you might want to go to the task manager <CTR+ALT+DEL> and see if there are any other Java programs running that might be interfering with limewire. I don't know if that is even possible, but it might be worth taking a look at. I'm not much help, but I hope you get it working soon.
