Assuming you're playing on PC and not a console, that command will work. I've always found it ironic (and perhaps a little cruel) that the biggest thing separating a PC copy from a Console copy of a game is the console command options, haha.

If you are, in fact, playing on PS3 of 360 then UAM's advice is the route to take. If you've gone too far past this point, then you are simply without the Black Star and will have to wait until next go around.

This reminds me, I need to do this quest on my Altmer. . . she needs the Black Star for all killing and enchanting I do!
