As far as i know the only reason for having trouble with the email registration system is that when using Autofil you get a blank space after the email address that must be removed.
If you registered your account then you must use the email address you registered your account with.
@MAGICDAVESHROOMI just went on the game and double checked that there was no extra spaces or any errors in the email name but I always get the error message: Registration Error. Failed to register. Please try again later. I have tried uninstalling and reinstalling the game but there has been no success.
