Hello! I just bought Gal Civ 2 Ultimate addition. I have a fairly nice gaming PC, so I turned up all the graphics and turned on all the cool features. I made the mistake of clicking the mixed vertex processing mode....

Now the game will not open, it goes to this black screen and glitches around for a while and will not open. I have reinstalled the game, the same issue is still present, I see no way of fixing this? I bought the game off of steam, any one who knows anything about this, please help! I see no way of unchecking it if I cant seem to get back into the game.

I had been looking forward to getting this game again for a very long time!
