Whenever I attempt to open Limewire 5.1.4, a screen pops up stating "Sorry, Limewire ran into a problem while it was starting up. This is usually caused by a problem during installation. Try downloading and installing Limewire again. If that doesn't fix it..."
The bug is:
LimeWire version 5.1.4
Java version 1.6.0_02 from Sun Microsystems Inc.
Windows XP v. 5.1 on x86
Free/total memory: 54600872/66715648

Does anyone know how to fix this?!?!? I have tried reinstalling Limewire but it does not seem to be working.

Start by uninstalling Java and then updating the newest version v.6update14

Download Free Java Software - Sun Microsystems

Use offline installer

I tried that...it doesn't work

Try steps 3, 5 & 6 here Fixes for Limewire (click on blue link).

If that does not fix it, then http://www.gnutellaforums.com/333278-post2.html
