The Trailhead unit Extending Reports using the AppExchange requires you to download the Adoption Dashboard.  I keep getting an error when trying to downlown that says "Package Not Found - The request packages does not exist or had been deleted.  Please contact the package publisher for assitance.  If this is a recently updated package, please try again soon".  
Any suggestions on how to get this corrected so I can complete my Superbadge?
