So, I've apparently sunk. . . a lot of time into this game since I started it earlier this month.

My computer more than meets the minimum specs and everything worked as expected. Now when I try to launch, I get a distorted purple-hued or green-hued (depended on where in the intro it is) launch sequence, followed by two copies of the load/start new game screen in the upper two quadrants of the game window. I'm not sure what changed- this happened after a computer reboot but I have rebooted the computer a number of times before. I've tried rebooting again several times and a few different display settings. No luck. Has anyone else run into this?
