Are you sure you got a completely reissued NW ticket? My guess is that UA endorsed the ticket over to NW for you and then NW, after entering all sorts of gobbledygook in its computer, accepted the UA ticket.

Since NW has the UA ticket (otherwise it wouldn't have allowed you to travel without paying the NW fare), follow the instructions on the link and provide that info for the UA ticket #. You should get the FF miles.
