The Sims 3 don't open after press"play" on launcher.

Hey folks, 

Actually it opens but goes minimized only. When I click on the bar's icon the game maximizes for a second, I hear the game's sound but the window is filled in black and soon goes minimized again by itself and there remains forever. 

The game is updated and runs no error.

No idea what to do!
