An error on our end caused your launch to fail. Try again a little later.

Trying to launch The Sims Medieval and this error message suddenly started popping up and the game won't launch.

Tried all the supposed "fixes": repairing the game, uninstalling the game, uninstalling the app, deleting the .exe file, clearing the EA app cache, changing the compatibility, pausing my firewall. 

Nothing has worked and EA support were pretty useless, anyone found a fix? Seems to be a persistent problem with the EA App.
