Final try at giving you some uninformed help.
You might have already done this, but after quickly skimming over your posts I didn’t see it (could have just missed it)
But have you tried a TOTAL uninstall of Democracy 4? Not just getting rid of the My Games folder, but going into Control Panel, Uninstall a Program, and deleting it there, and then getting rid of any file that may still exist afters in Program Files x86, Steam, SteamApps, common, Democracy4, and then also the My Games folder?
After that, try a reinstall?
Just a suggestion if you havent done it once already.
