I have bought a SecureLine license. The license downloaded okay, installed okay, and when I try to sign on, it just cycles for a minute and then says it’s disconnected and “Your SecureLine license has expired.”

You could try uninstalling ‘Secureline’ via contro panel Avast and Change. Untick Secureline and Reboot.
Then reverse process and tick to install ‘Secureline’ and Reboot. Then insert/apply your License. 
Any change?
