Thanks VPaulus,
i changed my monitor with my second monitor an Asus, it seems if i'm correct, that there was some conflict screen resolution...
now the game is working fine.

Have you checked if your Internet Security programs aren't interfering? Could you please try with them temporarily disabled? Yes i have only windows security, i've swicth off Windows Firewall, but the game is not working, i have always a black screen and have to Ctrl+alt+Cans...app does not respond...

Thanks for the reply,
i have all of my games on hard disk E:
-my SSD 120 GB C: hard disk is not for installing games, i removed the game and installed again on E:, but i have still the same problem, before when purschased the game was working fine.

Hello,
my problem here is that when i launch the game through steam i have a white window with the patch notes "version 1.0.2" when i press the OK button the game freeze in a black screen.
Any advice?
Thanks.
