STALKER - Shadow of Chernobyl keeps crashing.
 

Hi people, I have been a gamecopyworld addict for such a long time, but I just registered for the forums. I have a legal store bought version of Stalker.
I Have
Running W7 Ultimate.
64 Bit
4 gigs of RAM
AMD Athlon(tm) II X4 620 Processor (4 CPUs), ~2.6GHz
DirectX 11
2 x ATI Radeon HD 4670 Video Cards

It kept crashing in the begging of the game, so I googled it, and most people solved the problem by running the game with the app. LaaTiDo. and yes it helped. But now I am having the crashes again. I don't want to lose my game. Please help me. I have patched to the latest version, the game I mean. My video cards have the latest patches too.

Here is one of the error messages I get.

Faulting application name: XR_3DA.exe, version: 0.0.0.0, time stamp: 0x472217f9

theres aparently a problem with the original exe's protection not allowing the game to launch properly on some systems so it might be best to check out gcw mate

game works perfectly on my intel core 2 quad 2.66ghz
nvidia geforce 9800GT 1gb DDR 3 Directx 10
4GB ram
