Thank you Michael Gobin for your help! I am sure that you saved me and a lot of others much time and anguish!
SOS : as a matter of communication, in view of the form, presentation, that appears when you attempt to activate, you need to negative the first option that appears; i.e., tell us not to use the activation code box that naturally seems correct & and the intuitive choice, so users can correctly select “register full version” to obtain the necessary result. A better explanation would have greatly assisted!
