If you are missing the auto-generated scenarios (TV, Video, Audio, etc) then you have probably configured something wrong in the setup wizard. Re-run setup wizard and do not skip any steps. You must get to the end of the setup wizard, where there is a big button for "Start Using the System". After that, you will reload the router (don't force it if there are pending tasks) and regenerate all oribters. Both of these tasks should happen automatically at the end of the setup wizard.
