Had this bug just today.
Tried logging out and starting from another computer - no go
Tried to reset phases, however, it wouldn't bring up the option no matter where I went
Travelled back and forth between my house, Nar Shaddaa (planet side), house, ship, reset the quest several times, then finally went to my ship, hit Start and Launch and it worked. It would seem that patience is the key here (something I do not possess in great amounts ).
I would suggest logging out, playing another char for a bit and then trying again.
