Graphical Glitch (Green Glow)

[Blackdrazon]

I'm getting a weird green graphical glitch when in battle during Campaign 5: Mission 5 - The Vampire Lord. I suspect the game is trying to make it look like night with a filter, but instead it's making everything glow green like a paler kind of night vision. I can't find any mention of this problem anywhere online but any ideas all the same?

EDIT: I suppose I should mention that I'm on 1.6 and have more than the minimum requirements. I've never had a graphical problem before now, in fact (on this computer, but the problems on the other computer were different entirely). I'm updating my drivers just in case but the version I already had was only a month or two old. We'll see all the same.

EDIT2: No luck with the drivers.

could you post a screenshot?

Why not? It's a shot of setup but it's the same once battle continues all the way until I go back to the adventure map.
