Asked to re-enter activation code

I have AVG Ultimate. Which directions should I use?

I did a scan then saw that AVG needed to do an update. When I went to res-scan my computer after the update I got the message that AVG can't recognize my new license number and to click a box to re-enter it. Nothing happened when I clicked on the box. I then went into my AVG acct and saw that i have 720 day left on one section and "Your subscription has expired, and you now have only the basic coverage of AVG AntiVirus FREE and AVG TuneUp FREE. Renew now to get back your full coverage" in another section.

Please help

Marilyn, is the AVG PC TuneUp working fine or you still have problem with the activation?
