K...uninstalled/reinstalled...redid everything...same problem...
Checked log...found this near the bottom: "Impulse error when calling GetPlayerData in Addplayer. Unable to add player: [0] to game." Mean anything to you?
Thanks again...
Inside the same folder you found the Demigodlog file, there is another file called "Game". Its a .prefs file (Game.prefs). Open it with notepad or a similar text viewing program, and delete everything written there (Ctrl+A , Delete).
Then try again to launch the game.
It will probably do nothing, and your problem will persist, but try it anyway.
After doing that (or not) sent the entire Demigodlog file to Stardock support. Mail it to them, along with explaining them the problem.
They can be a lot more help than players of the game.
