Its not a 'program' that you download and run when you need too
The idea is that you access it online by logging in basically giving you a hub of tools and information so its all easy to access in one place
The very first thing that will happen is you will receive and e-mail to take you further after that you will go through the action guide all the way up until day 5 once you have done day 5 you will gain access to the online hub, initially you can only access the basic stuff needed for days 1-5
Just read the email you'll be fine
