Game doesn't Launch

[kaveh]

When I click plan in steam it opens the launcher when I click playgame in the launcher nothing happens, the launcher disappears and nothing else happens, restarted a few times, reinstalled twice.
Please help me.

NOTE: I had the game installed before the steam version release and it ran fine, It was only when I moved to the steam version.

DxDiag attached.

Have you gone into the options menu first? I had to change a lot of options back to the way I had it before.

I've already tryed that, what setting worked for you?
