Hey, I have problem with testing gamecenter integration in my game. I get "This game is not recogniezed by Game Center". I enabled GameCenter in "Manage GameCenter" tab @ itunnesconnect I can't click damn "Enable for this version" button in "Current Version" tab @ itunnesconnect, button is inactive all the time! Any ideas ? Cheers Flex
If you've done the things you say you have properly, then try deleting the app from your device, do a 'clean all' build in xcode, reopen xcode and build & run it on device. See if you can login properly after that. This fixed the issue for me when I was having the same problem.
Normally when I get this error, it is because I am logged into the Production server instead of the *Sandbox*. So, be sure to log out of Game Center before installing and running your app on your device (unless you are sure you are logged in to the *Sandbox*).
