Please make sure you bind your account to an email!

It was important to due so before to retrieve your account on other devices. Now, with Apple's new UDID rules, it is imperative. Your account is no longer bound to the specific device you are using and if you need to do a full reset, your account will be orphaned. You can retrieve it by using the code and email you used to bind it. If you have further issues, please contact support for help.
