I am owner of Black OPS since yesterday midnight, and I accumulate problems. Here I am before a wall that prevents me from playing so I'm looking for your advice. I obviously have a problem with my DirectX, when I launch the Campaign, the kinematics of the first mission begins to wobble and then when I see the head of that dear Fidel Castro: "DirectX encountered an unrecoverable error". And hop, black screen. In multiplayer, it's like I can play one or two minutes, then DirectX is any plant.
