Pilot Archive

I'm starting to collect all the ships I can. Anyway I got the first mission from the admiral Kreig fellow. I escorted the AT-ST like he wanted, and I received a completed message for the quest. When I talk to him though, he says "What do you want soldier?" like the mission is still on.
I can't get new missions and it's stuck!

What is going on? (I'm on shadowfire)
