Can't play Ironman Checksum switches upon entering game.

[Stefanos_P]

The correct checksum is display on the launcher (PXTU), however when I enter the game the checksum on the main menu shows: (UPQQ)

I have never installed any mods (MOD tab is even greyed out in the launcher), and I already verified the game files succesfully.

As a result of this the game voids achievements because it says the Checksum has been modified making it impossible to play Ironman to get achievements.

Please do a full **clean** re-install:

- move any valued save games elsewhere
- "uninstall" in Steam-CK2
- manually delete both the Steam/SteamApps/common/CK2 AND Documents/Paradox/CK2 folders
- re-install game in Steam, run a Steam Verify when done.
- start the game with no mods active and test

In particular make sure there are no files or folders left under either the Steam CK2 or Documents CK2 locations, before installing again.
