I am looking and we don't own this game anywhere, best I can tell..
it was some sort of gift for the beta or whatever, so we don't really have a copy of the game or a link or etc. or really 'own' the legit game
so it may be impossible to update.
the trainer is designed to try and work through patches, but it may be that the game updated quite a bit since the game seems to still be a work in progress.
at any rate, I have no way to access the latest version or update our game to the latest version at this point.
