Flashpoint: the Esseles quest glitch

I started the flashpoint esseles quest, and I was part way through it but my internet went down and when I went back on it was glitched I started at the start but it was part way through when I went to engineering like it asked me to i could do anything the ambassador wasn't there I couldn't see through the red shield. I reset the quest but it was still like that. Then I abandoned the quest and started it again but it didn't change. I don't have any idea what to do, any ideas?
