oh...I've seen this problem. Go into your config file in your games directory and change your settings on there. I think i can take a guess with what caused this...

Try deleting all of the small files in the games folder and redownload them.

[TwoTonChihuahua™]

Config file, and change which settings?
What do you think causes this?

(Will try that Muffin)
(Ok Tenshi, will try that too)

Try deleting your graphics_option.ini and open the game again.

Deleting the graphics_option.ini file, then verifying the game files fixed it, I'm in.
Thank you all for your help. (wipes brow)
