Sorry to hear it isn't working, though I'm not surprised.

Some versions of Windows give you the opportunity to run programmes in a "combability mode" - try that by right clicking on the games' .exe file and choose "combability" tab. I'd go for Win98 first.

Alternatively:

It's a long shot - but do you have both a graphics card and an onboard video card. You can tell by looking at the back of your cabinet - if there are two places to put the cable from your monitor, then yes.

As the computer boots up, you can press a button to acess the startup system. Usually it's F2, but it says so on the screen. Here you can choose the other card under "video" options. Once you save changes and exits, the screen go black as you've switched to the other card. Plug in the cable in the other slot and you'll see the computer open whatever operating system you have (my guess is Windows). Now you run with a inferior video card and can't do many of the things you could before, but maybe you can play MTW. You can always go back to the fancy video card afterwards.

Good luck - you'll need it,
