Sorry, what does "MOM implementation" mean?
In any case, your error is due to the game failing to detect that your video card can run the game. Normally that is because the video card isn't good enough, but yours should be fine, assuming it has 128mb of video memory (the 64mb model will not work). Have you applied the 1.2 patch yet?
If you have, or you do and it doesn't help, please run DXDIAG, Save All Info, and post dxdiag.txt here , down to include the Sound Devices only. Also post your Rome settings.txt and system.log files.
