Crash to Desktop whenever I throw a grenade!

[HalHalcyon]

I just got KOTOR 2, and it appeared to work fine up to Peragus mining station. For some reason whenever I throw a grenade, KOTOR2 just crashes to desktop. Ok, theoretically I could just play without ever throwing a grenade, but I always found grenades an essential part of playing KOTOR1 so I don't really want to do without.

 

I've never had this problem with other games. KOTOR 1 works just fine too. My system specs are all higher or equal to the recommended specs of the game. I am running WinXP professional without SP2.

 

My graphics card is an NVIDIA Geforce FX 5200, so it shouldn't suffer from any of the ATI bugs.

 

Ive also installed the patch, but the problem still persists.

 

If anyone could help me I'd be really obliged.

 

Cheers,
