Well, I have not find the solution yet, but you are right, I gave up.:-) I've already tried to open it in windows XP (and other windows versions) compatibility, but did not help. I will try to play with the drivers, as you suggest. Thanks for your help.
tassodan: well, you probably either gave up or found the solution by now but i'll write just in case. What you are describing is a compability issue. For this game open it in windows xp (win 98 should also work). If this doesn't solve it you can try an older version of direct x or upgrading /downgrading your sound/graphics/mother board drivers.
