When I first got the error, I updated the video driver, but that didn't solve it. I'm attaching the DxDiag info to the post for your review.

<t> Just bought and downloaded the game, ran the update, which appeared to install successfully. However, I get an error message that the Pixel Shader 3.0 and Vertex Shader 3.0 aren't available. I checked the driver for the graphics card and it's got Shader 4.0, so I'm not sure what to do. Please ...
