I'm using the same credentials that I use to login to this board/forum. My country is set correctly at the top of the launcher and at the bottom of the ROM run screen.
First, stop using your forum login details to log in to the game and use your game account details instead.
Second, make sure you
are setting your Region in the correct place - it's in the RoM launcher, not the GameforgeLive launcher, and you need to press the big red Region/Language button.
Third, if you do not yet have a game account, register one here:
