After starting the program a window appears where you can "program register" button. Then fill in the required data and receive e-mail the activation code sent to you.
Thanks for your quick response! I realized what my problem was for this simple prcedure. I use a password manager and I used it each time I tried to register this program but each time it wouldn't go to the registration page. When I manually entered my password, it worked and I registered the program. Strange!?!?
