Could you please post your log.txt files located in your game folder?
You can try this:
Delete that directory and in the steam common directory for DoF
C:\Steam\SteamApps\common\Dawn of Fantasy
delete or move the interfacedata.dat file from there then run the game, it will create a new profile for the game and generate a new interfacedata.dat file for it.
