I’ve been trying to follow the instructions about updating my key. I have a new one, but when I enter it into the License key block, nothing happens. I have completely uninstalled and reinstalled the program with a fresh download, but it seems to have kept the old key which has expired. How come it won’t accept the new key? :-\
Tried the uninstall utility for Avast? Try this and re-install again.

Have you copied key or entered it by hands? If you are entering by hands dont forget insert “-” and feel diferences between 0 (zero) and O (letter).
