Hi all. Seeing as one cannot submit online support forms on the Activision Support site, I'm asking my question here.

I bought MW3 off Steam on my laptop three months ago. Last month my laptop hard disk busted, and I had to replace it. I reinstalled Steam, and MW3, on this new hard drive. However, when I click "Play" on MW3, in Steam, I get a black screen, then I am immediately returned to desktop.

I can't start MW3 Single Player or Multi Player anymore. Can anyone help me?

Thanks in advance.
