Questline broken (Spoilers for Sith Warrior)

I just finished up my mission in Quesh, and was promptly betrayed by Baras and Draahg. My quest log told me to use my ship's holoterminal to contact Servant One, which I promptly did, only to be stuck looking at him on the holo with no dialogue, music, or anything other than ambient noise.

Last night I waited around ten to fifteen minutes with no change. I turned off the game and came back today, no change. So I tried it on a different computer. Still staring at me. I tried skipping the conversation and just went straight to Belsavis, which triggered a new conversation in which Servant One continued to stare at me. I can leave the conversation at any time, and can do other things, but I can no longer progress my story, which is really the only thing I'm interested in doing anyway.

If it's of any relevance, I'm a level 45 marauder playing on the Harbinger server. I've put in a CS ticket, but don't really expect to hear back from them any time soon.

Any tips, or am I just boned?

EDIT: The mission somehow fixed itself. I tried it several more times, then it just fired itself back up. It was on a different computer, but one that I'd already tried earlier with no results. Whether CS covertly fixed it or it was just a temporary local issue, I'll never know. Thank you for the advice though.
