Problem persists: avg internet security not loading

A previous problem thread (with Alok) on my problem seems to have been closed as my e-mails suddenly started to be returned unanswered.

 

INVOICE NO: 3702737552 of 12-09-2017.
A renewal for a 2 Years Licence, AVG Internet Security for 2 computers. 
I still have 1 year to run on this Licence.  How do I re-activate the installation please?

MY AVG INTERNET SECURITY IS NOT LOADING/STARTING.  THE BLACK FRAME OPENS WITH THE AVG LOGO AT TOP LEFT AND THE MINIMISE/CLOSE BUTTONS AT TOP RIGHT.  THAT'S ALL - NOTHING ELSE.

I have looked at https://myaccount.avg.com/en-gb/my-account-subscriptions but my subscription to AVG Internet Security is not listed ALTHOUGH it is shown in my order history as being valid within the time period of a 2 year license?

How can I re-activate the Licence please?

Best regards,
Nige
