Tutorial files won't load

[Dan25678638z3lx]

I'm trying to load the tutorial files but they seem to be empty, there are no objects in the scene or not even an environment. I am on the Beta version of Aero. Wht's going wrong? The on given on this page is an example: https://helpx.adobe.com/uk/aero/how-to/tour-the-workspace.html?playlistPath=/services/playlist.helpx...
