Registration IS very confusing, as there’s no link on the main page. But, clicking on the “Account” link at the top right f the main page brings up a page to log into your account, gmail, yahoo, etc. But first, copy the registration code! Then, after logging in to your email,the program will ask for your registration code. Paste it into the space provided and that’s it! Took me a while to get it but I got mine registered. Wish it was longer than a year, though.
