Odd crashing on LW start up

Alright, so here's the problem. Every time I start up limewire, it'll give me the splash screen, ask if I want to go Pro, then crash. It gives me a fatal error. Upon review of the crash details, I have what's listed below. I have tried completely uninstalling and reinstalling both Limewire and the Java Runtimes. But I cannot get it to work for the life of me. The problem started when I updated to the most recent version of LW. Everything was working fine before then, but that was a long time ago now because I haven't bothered trying to fix it in a while. Due to that, system restore is not an option. Anyone have any idea how to fix this?

Thanks.

The debug info provided by Limewire is below:

LimeWire version 4.8.1
Java version 1.5.0_02 from Sun Microsystems Inc.
Windows XP v. 5.1 on x86
Free/total memory: 557744/6074368

FATAL ERROR!
