There is a Norton Beta Portal LINK on the download page which FE asked us to click on in the first email that he sent to everyone doing the test. After clicking on that portal link, fill in the required boxes and download the Beta program. Norton then send you an activation code to your email inbox.
Regarding my previous problem about activating my other 2 computers, I was able to go into settings/administrative settings/network proxy settings and then cleared a proxy setting.This enabled me to sign in and activate my 2 other computers [Norton did this automatically] to obtain the 14 days trial period. [ I hope that makes sense, folks].
