If there any way, that anyone knows of, to do a fresh "install" and keep your previous "install's" statistics?(1) Scratch that. A new directory/extraction made no difference. Maybe it has to do with system files or something, but that is highly un-probable as you'd think the game would sprout a "dll problem" instead.
(2) Okay, this problem involves all Game Maker games. Um... anyone familiar with this error?

Edit:Alright, Google'd and found a...
discussion on this topic. It turns out that it may be an ATi problem. The strange thing is that, one minute, Spelunky worked, and the next minute it did not. I'll experiment with the ATi CCC and report any findings.
Once again, if someone is familiar with this problem, or has any insight, PLEASE POST
