I upgraded to the latest version of NIS. It asks to register. When I click on the button, it comes back with "We are unable to proceed with Norton Account at this time. Please try again later".

Try live chat on the keyboard it’s free, with a Norton representative on the link below. Vary the times of day you try, as it’s difficult to know when they are busy.
The Norton represenative may ask you to allow a remote access connection.
