Black Screen

[Artemis Kai]

Hello I just downloaded this game and started it up fine. I went to up the graphics because I was thinking it would look better if I upped them a bit. So I set res to 2560x1440, upped ground detail to max and set I think it was called Anti-Aliasing to 8bit and hit apply. I now have a nice black screen to look at even after rebooting the game. The music will play but the screen is black. Help please?
