This game is not recognized by Game Center
I'm having a heck of a time with this. It works in the simulator if I create a new sandbox ID by starting within my app. The Game Center app will show me as logged into the sandbox under that account.
If my app is running, then the Game Center app shows one game in the Games tab. Otherwise it shows none.
But when my app launches subsequently, it pops up "This game is not recognized by Game Center."
I also can't get it to work on the device, even if I create a new identity starting in my app.
I couldn't find anything in the cocoa lists (Apple's search just failed, google site: search returned no results, and a plain google search turns up most people talking about jailbroken phones or mismatched Bundle IDs. My bundle ID is set, I've tried with and without the gamekit requirement, and nothing makes this easy).
