Norton Utilities - Stuck in Re-activate loop

Effective Sunday 26 Sep, both my PC & Laptop's Norton Utilities (was Premium, now Ultimate) have been stuck in a logic Loop: Run Norton Utilities scan, get a list of errors and a message to Re-Activate to repair.

I follow the instructions (go to account, Subscriptions and ensure Automatic renewal is on).  Does not fix it.

Reboot and retry all of the above - does not fix it.

Clean re-install of NUU and follow the above as it require Re-Activation.

Now stuck for choice. Any help gratefully appreciated.
