Return of Reckoning

As the title says, I am unable to access the auction house at all. Right clicking on the NPC (the female one in Karaz) does nothing at all. Neither of my characters, both slayers lvls 10 and 13, can access it. Works perfectly fine for my friend, who is playing a rune priest, if class somehow has anything to do with this. Neither of us are running any addons at all.

Sometimes it happens, just relog the game.
