Contact your Partner Manager or Support so they can update your email address. Due to security, email is not a setting available to users, and only authorized QlikView people can do that.
I've no access to the support:
If I choose continue as Guest I've got this:
"Welcome Guest user
Please log in using your Qlik.com credentials to benefit from all features of the Support site."
Why not using the procedure as every other page: Users can do that. What magic is a service member doing with this email?
