Quest: The Azure Key (Rogue)

Hello Guys,
I just handed in the quest Encoded Fragments to Archmage Xylem in Azshara, but I was not able to obtain the following quest which should be The Azure Key, a quest for the Sunken Temple. Right now he is not talking to me at all by rightclicking. Also tried logging in and out multiple times. Do i have to do something specific to start the new quest or can u maybe try to reset the NPC? Characters name is FacetoFace.
Thanks in advance.
