when opening a L5 set, or more generally a set that isn't inside a project, if i go in the File Manager, i have a line saying "This Live Set doesn't belong to a project" (in french).
if i click on "project", i'm directed to a page explaining in english what a project is.
if i click on the "Home" icon, i'm directed to the lessons for alpha testing, in english!
it seems that my lessons are those for alpha testing (and i have the Live 6 Lessons" Pack installed).
