Norton 360 - "We are unable to proceed with Norton Account at this time. Please try again later"

The above subject header is the problem I'm having. About a week ago I received this advice:

 

Hi 

   Please go to https://manage.norton.com> sign-in with your Norton account email and password-> go to My Account -> under products select your active Norton360-> remove the license next to your computer by clicking on trash can->open N360->click on support->subscription status->it'll prompt you to activate->copy the key from the same page (from where you've removed the license)->activate N360->now logout from the manage icon->try to activate the backup.

 

you can identify the computer using the device name, to find the device name press the windows logo and pause/break on the keyboard at the same time and refer the computer name.

 I followed this advice, and removed both active licenses that showed. I then activated my account by copying the key as instructed.  And after logging out of Manage, I tried to activate the backup for the hundredth time. The result? The exact same message. I cannot activate Online backup, and I want to know what I have to do to get it. I have been getting this message ever
since immediately after installing Norton 360 on this computer. I have wasted countless hours trying to fix this. NOW I WANT TO KNOW JUST WHAT I HAVE TO DO TO GET BACKUP WORKING!
