Hi! I played through the demo with no troubles, and so I bought the full game. No trouble particularly, but when I get to the end of the demo section, the screen fades to black and then crashes to the desktop with a message along the lines of "Access violation at 0x10083DAA (tried to read from 0x00000000), program terminated."
Irritating enough. However, I tried changing the game to running in a window, and now it won't even run at all. As soon as I run the program I get the same sort of message and it doesn't get any further. So now I can't even get to the setup menu to reverse this mistake.
