Penumbra Black Plague causing blue screen

[Contrarium]

I took my save files from this computer and transferred them to another (family desktop) one, and downloaded Penumbra on Steam to that computer. It seems to be working fine on that one, which of course is wonderful! ...naturally I'm also trying to get it to work on my computer still. The save files are completely fine, but loading them is the problem because it causes the game to crash on the laptop.
I'm willing to bet it is driver problems causing it. Maybe an update is in order?

Another interesting tidbit to note is that when I installed it, Steam never asked for the game content conversion. So there's always that.
