Problem with Windows 7 and Mission Generator

[Mongo]

I've recently installed Windows 7, and have reinstalled TOW2:Kursk.

The game loads up fine, and I can get into the Mission Generator, but when I try to generate a mission, an icon comes up about generating a mission, then stops. And then nothing.

No problem getting into the campaigns. They load up.

I've tried resetting the Options to default, but no difference.

And when I've had a snit fit and started uninstalling the game, the game starts up and I can generate a mission!

Does anyone have any suggestions?
