It means that the backup codes you submitted didn't work. Please double-check if they are correct or expired or not.

Notice:
Each backup code could only be used ONCE. If the backup codes are gray when you try to get them on ea.com, it means they have already been used and have expired. Please click the button "Create New Codes" to get black codes that mean they're valid.

After you check that, please withdraw player(s) and submit account info(including email, password, and valid backup codes) again.
