Unable to start The Guest Relations questline

And idea why I would be unable to start the “The Guest Relations main questline”? Alyx is (as far as I know), where we start, with a quest called “Lost and Busy”. But she has nothing for me, nor is there anything available on the noticeboard next to her? I’ve exhausted my search of Google, the forums and places like Wowhead. Am I just being really thick here? Thanks in advance for any help given!
