I got this one too. "An error occured while retrieving the repositories. The web service may be temporarily down." My solution was to manually insert the URL for Google Streets and Virtual Earth Streets. I do not know the URL for the others (satellite imagery maps and Hybrid maps) so I don't have them for now. MM 1.4x spoiled me with all those other maps to chose from, MM 2.0.1 only gave me OpenStreets until I manually typed in the URL for the other two mentioned above.
