Yep. You were right. For some reason the Java 6 update 2 runtime causes an exception in Limewire. Once I uninstalled it, leaving java 5 update 11 by itself, that seemed to resolve the issue.

Holy crap, that's TERRIBLE. I really hope the Limewire developers can fix this issue soon, because I really don't want to be limited to an older java version only so I can run LW. That has GOT to be fixed.

Anyways, thanks alot, Birdy!
