Thanks for the help - we'll need to keep plugging away at it.

As I mentioned, I uninstalled the video drivers and went back to the 30.87 drivers, and it didn't improve the problem. Video card is at default settings - no overclocking, no refresh rate fix (in fact, none was needed with the 40.72 as they have built-in refresh rate support, though I didn't need to enable it). I've uninstalled and reinstalled the game two or three times now, no change.

I'd like to check out the uninstall guide, but the link isn't working.
Again, I appreciate the help - I'll keep plugging away at this end, if there is anything else you can suggest please let me know!
