Details of your Issue:

I made an account and played it until level 5 on my Kindle Fire. Than i got a new phone and logged into my account on that, and it worked fine. After the last update, it logged me out of my account on the phone, and when i start it up says i need to start from scratch. I hadn't got the last update on my kindle, and so my game data is still there on that device. When i'd made the account originally i'd linked it to my email. However, i forgot the @ symbol in the address. The system took it and worked regardless (like i said, it let me log in on my phone to the same account) but after the update, it now says that it's an invalid email address without the @ symbol. Since the symbol wasn't in the email address the account was linked to originally, it's not finding the account and saying it doesn't exist.

Is there anyway that i can change the email associated with my account? I tried through my kindle, but the only options i see as "Login as" and "start a new account" No option to change the email associated.
