Can't Update to 1.3.1

[Romulator]

Well, if you can recall your order number which you should have received when you purchased the game, you may be able to try here: https://shelf.frictionalgames.com

There is a service available if you cannot recall your product number. If your problem persists, I recommend contacting jens. He should be able to help you further.

Apologies for the "site you bought the game" issue. As a Windows user, I'm able to download from there.
