Game crashes just after pushing "Start" in briefing

[Tolkien]

Hi all,

 

I bought the game yestarday at Steam and I updated to 1.008. I set the graphic options to ultra and then tryed to start a quick mission. No luck, everytime I try to launch a mission (no matter if campaing, quick, etc) the game crashes and brings me back to desktop.

 

I changed the graphic options, resolution, tryed to play in window instead of fullscreen... nothing worked for me.

 

I have a W7, I7, 6gb RAM, Gfx 770 4gb vram.

 

Anyone have some clue about that issue?
