@ vuenxx: Sounds like a DirectX driver issue. For some odd reason it cannot initialise your graphics card. This is nothing related with Greenhawk's executable game.

Maybe we can see what kind of DirectX version you're currently using it - type in Command Prompt dxdiag and paste all the following output here. A possible solution would be by running the executable in compatibility mode for earlier versions of Windows (Right-click on executable specific, Properties and there you can find the compatibility options).
