Limewire & Jaguar Hard Crashes

I installed Jaguar (10.2) shortly after it was released and was very impressed with how much it improved Limewire's performance. Limewire was much more responsive!

Unfortunately, since yesterday, I suddenly started having serious crashes when running Limewire. The app will launch, but after running anywhere from 1-10 minutes, it will crash and crash hard. The entire system freezes up, I cannot force quit, and the only alternative is a hard power off and reboot of the system. Sometimes I still have my mouse pointer, but I can't click on anything. Sometimes I can start searches and even initiate downloads, but then things will lock up after a while. This is very repeatable - I've had this happen over five times since last night.

The last time I was able to run Limewire successfully was around Sept. 02 or so and I have not installed any new software since then. I have no idea what might be causing this. I ran Norton Antivirus and it came up empty. I've even downloaded the Limewire installer again and installed everything from scratch. The crashes occur even if I'm not running any other app. Here's my system:

PowerMac G4 400 AGP (stock except for extra RAM and an additional internal hard drive)
448 MB RAM
OS X 10.2
Limewire 2.5

Any ideas out there? Thanks in advance!
