I think you're not setting the Denom Configuration for the game. If you don't do this, if you go to Game Setup, it will say there's no games to configure. While it says Game Setup, it really isn't. In most games, you don't actually configure anything there anyway unless the game has a top box with the option to disable it, like Wizard of Oz, and you would disable the top box in the Game Setup section. But with most games there is nothing you actually setup in "Game Setup".

That't really where you are setting up the game. But until the Denom Configuration is set, if you go to Game Setup, it will say no games to configure. And even afterwards, while you would then be able to go there, you generally don't have any settings there you can, or need to configure.
