Sniper Challenge crashes on startup

[TrondMC]

Hi.

The game crashes on startup, sometimes after a few seconds, sometimes after showing the red sniper challenge screen.

I have an intel 960 processor, 6 gig ram and an Nvidia GTX680 gfx

Have tried to:

• update to lates GFX drivers,
• restart Steam,
• restart windows,
• deleted and reinstalled game,
• change the game gfx settings from low-medium-high-ultra and some custom things,

I hope someone can help, I'm at my wits ends ..

ps. Have some "hmsc_4550_crash_2012_8_3T13_59_8C0.mdmp" files if some devs want em.
