First of all did you check your event view for the actual error? (Start->Control Panel->Administrative Tools->Event Viewer)
Check your video drivers to see if they are the newest and any other dirver that is related to your computer... I use this to keep my dirvers updated

Second see if Demigod has a minidump feature. Sins has it but I am not sure Demigod has it.
Third Head to the support site of http://www.gaspowered.com/ as Stardock did not do any of the developement (don't know if they actually did any) and email the tech support staff.
