Maybe my comment was forgotten but I need some info about the problem because it will maybe broken the game if it continue blocking :/
Well, the only thing i've did it's each update is that I delete the folder of the old version and create a new one containing the new version of the game. My saves don't disapear but I don't know where it save... maybe it's AppData or something like that
EDIT : After 30min i've tested to move my saves and test something but in the end the error still comeback.
