locate this file called Game.prefs under this folder C:\Users\"your_user_name"\Documents\My Games\Gas Powered Games\Demigod and delete it. This should fix your problem, however it will reset your favor points and achievements.
It should fix the problem, but it will only reset your single-player and lan favor points and achievements. The multi-player points, etc, are stored server side. Plus, once things are working again, you can edit the game.prefs file to give yourself as many points as you want, but they will be single-player and lan only.
