Then try to make that folder. It doesnt matter where you instaled game, destination folder for in game settings is same, as i said documents/.../kings bounty princess/$save , there must be where save game files go. In that folder kb-p are screenshots, and game.ini file which defines monitor resolution in game, so if you game works that folder must exist somewhere. Try finding game.ini file or making some screenshot and find it on your hard (it in .bmp extension).
If that doesnt work i cant help further
Good luck man.
