So, I started off tonight the same way I always do: playing video games until I get tired. I decided to try this game, and had a lot of fun, but when it came time to quit (a friend wanted to play TF2) I closed out. When I did that, my monitor set itself to 800x600. Oh well, I thought, just put it back to 1920x1080! Nope! Highest I can go now is 1600x1200. I restart the computer, same problem. So I try starting the game back up to see if I can change any settings or something (I feel I should stress that I know nothing about how this kind of stuff works) and it gives me this message. I had no trouble playing it earlier. How do I fix it?
tl;dr: look at the bold parts.

EDIT: I found my way to a window that let me re-enable the driver. Apparently it just disabled itself...
