Re-registering

Hi - I guess this is a stupid question, but I need to ask!!
I’ve been with Avast (free) for a year and have to re-register, I’m told (pop-up box) The “show details” link doesn’t work, so I’ve been trawling around to find how and where to re-register.

Is it the same thing as: “Avast free antivirus licence resend”?
