Protection Fault

Didn't see anything on the sticky-notes, so, hopefully I can get some help by posting it myself.

Build UT2004_Build_[2004-11-11_10.48]

OS: Windows NT 6.0 (Build: 6000)
CPU: AuthenticAMD Unknown processor @ 2210 MHz with 2047MB RAM
Video: NVIDIA GeForce 9800 GTX+ (9621)

General protection fault!

History: SkeletalMeshGet <- USpriteEmitter::UpdateParticles <- AEmitter::Tick <- TickAllActors <- ULevel::Tick <- (NetMode=2) <- TickLevel <- UGameEngine::Tick <- Level KF-Icebreaker <- UpdateWorld <- MainLoop <- FMallocWindows::Free <- FMallocWindows::Realloc <- 4C576C61 0 FArray <- FArray::Realloc <- 0*2 <- FMallocWindows::Free

The OS and CPU that it lists are wrong. I'm running Windows Vista 32-bit, and my CPU is an AMD Phenom 9500 Quad-core. Plus I'm running on 3 GB, even if it says only 2.

I usually tend to get these crashes/fault warnings by using explosives, but mainly whenever I use fire of any kind other than world-fire. Just thought I'd bring it up and hope for the best. Yes, I've verified my game files, and yes I've tried a fresh reinstall of the game. Nothin' has worked so far.
