Hey i could really need some help. Every time i try to launch the game the screen just turns black and than goes back to the desktop with the message X-Ray Engine 1.6 doesnt work anymore. If i look in the details i can find out that it has something to do with the Xrcore.dll.
So here is what i've tried:
Reinstall
Run as Admin
Compatibility Mode
Run the 2 different exe's
New Shortcuts
Re-Download
Deleting some tlx files or something like that (don't worry i've reinstalled after that)

So yeah... no solution found yet..
My Specs:
Win7 64 bit
AMD Phenom II X4 840 (4x3,2ghz)
8 gigs of ram
Nvidia gtx 460

So some help would be really nice :)

Ok so ive fixed that problem. For anyone who has the same problem just delete the user.ltx file in the stalker cop folder under documents.
Now i have another problem. i get in to the menue and "start new game" and chose a difficulty. After that the game just freezes at the loading screen. every time.. any advice ?
