Game Center login error

I'm having the same problem as well. Seems as if my Apple ID has lost the connection with my Game Center account.

I've been having the same problem, every time I login It takes me to the create a new account page, 😟 helpp

I have tried to make a new account under the same username which works. Only problem now is that I don't have my friends and achievements anymore...

Seems like everyone has been having this problem every since 1/30/11. I have it too, don't know what to do.

Here is what I posted in the other thread about this issue that worked for me.

Make a new account while in sandbox mode. Once done, sign out of that account in game center. Close game center and kill it's background task. Now open a game that uses game center, which should prompt you to sign in. Do so, and you should now be back on your original account.

Hope this helps.

This seemed to work! Thanks very much!

omg i had the same problem and I created a new account with the same apple ID and....all my records are gone! anything I could do to regain my friends and scores?
I have tried TehMaster's method but it doesn't work for me....:(

I have the same problem and that solution worked for any app i already have in game center, if i try to install a new app with game centers its keep sending me to sandbox!!!

Worked fine for me... even when installed a new game.

Problem is back when I installed a new game. He now signs in the account I created in sandbox mode. When I log out of that account I can log back in to my original account but when I launch a game the game prompts me for my Game Center details and when entered he signs back into the sandbox account. Any more ideas?

I also have this issue. It's started when I start StarDunk. I've played in past and I've also more achievement. I try to create a sandbox account with the same access of my normal account, and another sandbox account with another mail, but with some games, it happens.

It would be nice if a Apple rep took a look at this problem.

I'm experiencing the same problems. I hope someone can help.

I have the same problem, signing out and back in only works until I install a new game

same problem, signing out and back in only works until I install a new gamecenter game.
