Hello, I'm the programmer for this game. I'm glad that you got it working with Rae's help. I'm also playing the game on Windows 7 64-bit, though I haven't had to use compatibility mode. By any chance, do you have Windows Update disabled? I thought that players normally wouldn't need to install any extra things to play the game.

You might want to manually run Windows Update at some point to catch up on general security and compatibility stuff. There were a few programs I couldn't run until I had updated my system. (Also, I'm stuck with Windows 7 due to old hardware.)
