Chain crash ns2

[G0PA]

Hello, I'm French, I will do my best for you to understand.

I've a bug with the game : natural selection 2.it's installed, none problem and when I want to start, it opens and it closes directly.
I checked the cache, reinstalled the game, updated pilots, follow a tutorial => DXSETUP but nothing, it continues to open and close.

I've too that bug with other games like : Dragon's Propeht or Panzar... etc

Do you have a solution ?
