Hi Ryan,
Thanks for reaching out. I’m sorry you’re having a hard time getting set up with Pro…the good news is, it will work on .org or a .com site!
The spot for the license key actually won’t appear until you have installed and activated the plugin, which you can do by following the instructions here.
You should have a main events page now, with just The Events Calendar installed. It won’t appear in your list of Pages (I know that can be confusing!) but you can get to it by going to yoursite.com/events. Which methods have you tried from the article you mentioned? The shortcodes won’t be available until Pro is activated, but you should be able to go into Settings > Reading, setting “Front page displays” to “A static page”, and then selecting “Main events page” as the front page. If this isn’t working, could you please send me a screenshot of what you see on that screen, specifically of the “Front page displays” setting?
Thanks!
Jennifer
