Help with errors when playing cinematics¡¡¡¡ :-( (ayuda)

When begins a cinematic I hear the beginning of the sound but the game will close, first I tried removing the cinema to start the game and it worked, I entered the game, but I cant play the campaigns because it begins with a video, that file crash my game.

I think the .webm format is the problem, somebody know how can I fix this??

I use Win 7 Home Premium

Video Card Radeon ™ HD 7690M XT
P: Intel Core I5
DirectX 11

Uninstall 3rd party video codecs like ffdshow or any codec packs. If that works you can likely configure the offending codec to not interfere with the game.
