You left out one important step i.e., deleting records form the "load_list" table prior to your next load attempt.
So execute the following via SQL command-line or conductor UI:-- empties the table. You can also simply add a WHERE clause to more selective about named graph iris to be removed.
delete from DB.DBA.load_list ;ld_dir('/usr/local/virtuoso-opensource/share/virtuoso/tmp', 'wcmcPeopleAddress.rdf', 'http://vitro.mannlib.cornell.edu/a/graph/wcmcPeople') ;
