GMax error

Does anyone know how to take care of this start up error in GMax
"Interactive 3D Renderer initialization failed.
Please check your device setting by using the -H command line option"
I'm not sure what it means by "-H command line option"
I now get this after I first ran gmax and set up the preferances.
Any ideas anyone.
