Try reinstalling or, if necessary, uninstalling then reinstalling your video card driver. That should reset the pointers and allow it to work. Dxdiag should show your version as DirectX 9.0c (4.09.0000.0904).
Most games that install DirectX will allow you to cancel and continue with the rest of the installation. If you are already at the latest release, that is what would be best to do.
If all else fails, you would probably have a Restore Point created at the time you did the initial installation of the game. Restore to that point.
