Thanks for the replies, guys. All sound like possible candidates for trouble, I agree.
I've re-installed twice now and not getting any results.
My drivers have recently been updated, and I don't think DX needs updating since I was just playing Doom3, Half Life 2, and Eve Online all on max settings. DirectX doesn't seem to be an issue for my computer right now.
Also, if it has problems then how was I able to open it up in the first place to make a small map?
