HI Guys, Just wondering how I go about changing my email, seem to do it in the setting section but keeps defaulting to the old one which I no longer have access too.

Hi.
Follow these steps:
Add the multi user app
Add your new email address
Make new email address admin
Logout 
Login as new email address
Open multi user app
Delete your old email address
Uninstall the multi user app.
