Useless. Doesn’t work with my account.

I have an anual account with Lynda.com and can access my courses and playlists fine using a web browser and with my iPhone app. But when I try to use this Mac app version of Lynda.com, all it says is “You don’t have any downloaded courses yet.” That’s it. There are no controls, menus, links, swipe gestures, nothing. Its completely unusable with a static useless interface. What’s up with that? (I’m running El Capitan, v10.11.5)
