Plutonium

Thank you . I already did it but now when I enter iw3 I go offline and enter the game or load the bar and it throws me an error.

directx error that's all it says.

I just installed mw3 on my pc and just a few moments ago the plutonium.
I already selected the location of the mw3 in the launcher but when I press play it sends me this error.
