When I am trying to complete one of the sections of Trailhead for Basic Developer trail, I get following error message when checking for results: System.DmlException: Insert failed. First exception on row 0; first error: PACKAGE_LICENSE_REQUIRED, License Required: []

Trail that I am working on is: 
Developer Trail - Beginner  Formulas & Validations  Using Formula Fields  and it is simple checking how many days have past since last Activity Date on Account. 
I have tried logging out and logging back in, as well as disconnecting my dev org and connecting it back to Trailhead, and still doesn't work. It did work however for some other sections that I've tried though. Any ideas will be more than appriciated.

I have a lookup to user to get say the Manager name. 

I would like to automatically populate the Department, Location and Phone for this user when the person selects the user.

How do I do that?

Can it also be done pulling for Active Directory?
