Why doesn't my sith inquisitor classquest go on after Trais?

I played the game and therefore the Story until Taris where I did follow the classquest until the Point when one bound the ghost of Ashara's ancestor. Having not fully finished that quest (returning to my ship is lacking) I left the game and came back after the "Fallen Knights" update. Suddenly, I had no classquest anymore and found no indication on how to go on.

As the storyline is of huge interest for me, I'd like to know if any of you had similar Problems and/or do know a solution.
