Hi gaet
Now you know some part of Java crashed (which one, I can't say--the limewire.crash.log usually starts with a date and time, and then shows a crash type and lists the threads. One of the threads will say 'crashed'. I usually scroll to the bottom of the log and work up to find the latest crash).

If you know how to do the usual Safe Boot/Repair Permissions/Run Software Update, (and repeat), that should clean up your system.

If you still get crashes, copy and mail the last log entry to bugs@limewire.com, and clean out the old limewire prefs (including old incompletes) and start with a clean install.

Sure hope that helps!
