I was playing the demo, it was really good, but when I got to the magma area, I got a black screen, then an error window popped up about the file. When I clicked on the game, it wouldn't let me because the screen showed lines of just # and the word "error," until I had to select the "abort" option and it kicked me out completely. I don't know if I'm the only one with this problem or if there are others.
