DX9 not working for me

[deltamatrix]

I will seem dumb but the DX9 will not work for me. Always get this error msg:

---------------------------
Adventure Game Studio
---------------------------
There was a problem initializing graphics mode 640 x 400 (32-bit).
(Problem: 'Direct3DCreate failed!')
Try to correct the problem, or seek help from the AGS homepage.

Possible causes:
* your graphics card drivers do not support this resolution. Run the game setup program and try the other resolution.
* the graphics filter you have selected does not work. Try another filter.

I have tried all varieties of resolutions available and it still don't work. Have I missed something?
My GFX card is Geforce 6200 and I got directx 9.0b installed.

Please help

Upgrade your DirectX and try again.

V9.0b was an ancient fossil, V9.0c was released long time again (also, it has gone through meny minor version changes).
