When you subscribe a new link will be sent to your email and you must access the videos through that link and not return to the original page to view the tutorials. Otherwise, it will again ask you for your email. If you don't see the links to the videos in your inbox, please check your spam folder as some customers have found them there.
If you do not see the email in your spam folder, please try using an alternate browser when requesting the email. Some customers have had trouble on our site in certain browsers, and this simple change, fixed the error.
