Well I start to play UT and a few minutes into the game it crashes on me and I get the following:

UT2004 Build UT2004_Build_[2004-09-21_19.13]

OS: Windows XP 5.1 (Build: 2600)
CPU: GenuineIntel Unknown processor @ 1796 MHz with 255MB RAM
Video: NVIDIA GeForce2 MX/MX 400 (6177)

General protection fault!

History: KBodyGetActor <- BodyGetDoubleRate <- KBuildPartitions <- KWorldStepSafeTime <- KTickLevelKarma <- TickAllActors <- ULevel::Tick <- (NetMode=0) <- TickLevel <- UGameEngine::Tick <- Level Primeval <- UpdateWorld <- MainLoop <- FMallocWindows::Free <- FMallocWindows::Realloc <- 676F4C57 0 FArray <- FArray::Realloc <- 0*2 <- FMallocWindows::Free

Can anyone help? I would appreciate if you post back.
