I downloaded Sandbox of God, unzipped it, and played it for a few rounds, then quit. Now I've started it again, and it won't load the saved game. I click "Load Game" and nothing happens. The saved game file is right there in the folder with the game program. I even tried opening 'sandboxsave' directly, selected 'The Sandbox of God.exe' from the "Open With..." dialogue box, but no luck. However, it will load my high scores, which makes the whole thing all the stranger.
