James -
AutoCAD Civil is the neutered step son of Civil 3d. It is lacking the underlying Map engine.
If you migrated to Civil 2010, you also gave up your right to run Land Desktop Companion. The object enabler fails to load and hence to display Land Desktop points and contours in Civil 2010 (land desktop objects). Is it by design or defect, I don't know, don't care - but its been a pain in myside since we dropped a number of seats to Civil.
