Nope, I put the files into my Windows partition while was running OS X.
Anyways, I fixed the problem. Go into Tools > Options, then click on the tab labeled "Performance". Where it says "Video Acceleration" (towards the bottom), click "Advanced". You'll then see that the 'Use Primary Surfaces' box is checked. Uncheck the box, and everything should be just fine.
Huzzah for solving my own problem!
