Reactivation following an automatic update email

Keith,
We are sorry to hear about the inconvenience caused.

Kindly run the downloaded file and enter your license number to proceed with the installation. Please, feel free to let us know if you require any further assistance. Thank you.

There is not a reactivation choice in the options menu.  AVG is running but perhaps not as well as I had thought. I have Windows 10 Home and plenty of disk space.  Should I install the files from the email link and update the licence, or do I need to do something else?  I note that I had an update in October 2016, so this one was unexpected.
