in cvpcb/Preferences/Configure Paths what do you have listed ??
since your watching tutorials... lets start from scratch. ok? we make a new project ... first thing we do. check your PATHS. > Preferences/Configure Paths we want to see... that your list is populated. it "should" look like the picture that was posted by@sembazurucde here> http://docs.kicad-pcb.org/stable/en/cvpcb.html#_footprint_libraries_management
we do NOT want to see a list with $KIGITHUB listed as the location of files.
we DO want to see a the contents of this file "renamed" as... fp-lib-table
its important that both files be in your kicad user directory/folder.
doing that... you should be a happy camper...
