stroemtomas

I'm doing the Magecraft quest and was teleported by Sanath Lim-Yo in Azshara up to Archmage Xylems tower. Though when i got up there, in a lapse of concentration, i immediately talked to the guy in front of me who then telported me down again. And now i can't get back up to talk to Xylem. Seems like the Sanaths teleport was a one time thing. Can something be done?
