Issue with Windows 10

Hi, I have updated to Windows 10 with which I had an issue with the home screen flashing.  One suggestion was that it was Nortons that was the issue so I deleted Nortons however I now can't reinstall as the following message appears:  The subscription has been disabled and cannot be renewed. (-1006).  

My subscription is paid for and active as shown in my account.  All 3 computers are listed,

Not sure what to do???
