I can't remember when this started happening...

Whenever I try to use Limewire one of several things will happen:
1) It starts up and is used normally
2) It will startup but crash at a random time
3) It will startup but crash at a random time and freeze my computer
4) It won't even get passed the loading window... It will crash

I had recently downloaded and installed Java beta 1.6 but clumsingly left Java 1.5 still installed. I uninstalled Java 1.5 but no luck. I then uninstalled Java 1.6 and reinstalled 1.5. No Luck. Then, I tried reinstalling Limewire (not the current version). No Luck. Hoping that this was some sort of bug with the older version of Limewire, I now have the most recent version of Limewire (4.12.3). No Such Luck. I have already tried removing all Limewire preferences which gave me nothing. I am certain that this isn't a virus.

On a seperate note, I have noticed something interesting in the Limewire folder. It turns out that Limewire produced a log file every time it crashed. I took a look inside each one and they error most of them game me was this:
EXCEPTION_FLT_DIVIDE_BY_ZERO (0xc000008e) at pc=0x00caaa53, pid=328, tid=2920
Something's wrong with the Limewire.jar file.
Unless I can find any solutions here, I'm going to try to fix the problem myself...

ANY SORT OF HELP IS APPRECIATED...

O, and by the way, Zone Alarm and AVG give it access...
