Age of Empires 2 has messed up colors on this rig

I've got vista ultimate x64, and and I'm seeing wrong colors in this game. Like, there is red and stuff in the grass and other places where it shouldn't be. I don't know if it matters, but I'm also using at 24" 1920x1200 monitor. It works fine on the xp pcs, but running in compatibility mode for xp didn't do anything. This is the conquerors btw.

Yeah, i have the same problem, just change the screen resolution back and forth and quit the game and start it again a couple of times and it will work.
