Unable to add Map to Garmin Edge 1030

Hello,

I am trying to add the Routable Cycle Map of the United States on to my brand new Edge 1030. I have my Edge connected to my Mac and the Garmin Express application. After selecting Manage Maps, choosing the map I want to download, clicking 'Apply Changes', and continue; then the map starts to load but always fails. The failure message reads 'Some Changes Not Applied' in the pop-up. On the Garmin Express app it says 'There was an error installing the update.'
