You should remove the game.cfg from the zip file, that's what's causing the crash. It seems to be from an incompatible version. Ideally, you should delete game.cfg, start the game, clear the high score list if necessary, then quit. This should produce a clean game.cfg with no scores on it that you can safely package with your mod.

Having said all that, there may be a way to make the code handle it better but I'm not sure when I'm going to get around to working on this again.
