After I beat Zez-Kai Ell, learning his form and have a quick chat with Kreia about my new soul sucking technique, I'm given control of my character and the option to add party members, which I use because HKs frightens me.

I make my way to the Ebon Hawk, through two, IIRC, waves of assassin droids.

When I enter the ship, it's empty and I still have my party. I can't interact with the star map and HK's room door is sealed not interactive.

 

I previously had to use the save editor to gain influence with the Exchange: one of my quests didn't register as finished.

I tried to look up again but I found nothing relevant.

 

Nar Shaddaa is my first planet. I have the restoration project on, but not Gizka's.

 

Help would be very appreciated

I'd say your best bet to find a solution would be to check the forum boards of the restoration project rather then here..

The only thing I can really suggest is try using a slightly earlier save and going through it again, see if the problem repeats. Sometimes the glitches caused by the restoration mod don't always occur again.
