If you are experiencing crashes, please download this zip file and run the .cmd inside. It will gather a variety of debugging info and generate another zip file in My Documents\My Games\Gas Powered Games\Demigod\reports which you can email to support@stardock.com. They will then pass the info on to the developers if they cannot help solve the issue.
If you're getting BSODs though, that generally indicates an underlying driver or hardware issue.
