How odd. I had someone report a similar error, I think the file loader gets confused if you have a lowercase 'game' in the folder directly above the game. I will figure it out and fix it in a stable manner in 0.3, but in the meantime, your main options are either; move the game up 1 level so it's not in a folder with "game", or edit startupFunctions in DivineDawn-0.2-pc\game\dawncode, replacing "if "game" not in os.getcwd():" with "else:". I could also try and send the edited file if you want to just replace it instead of editing it yourself.
Sorry for the trouble.
