Im on the quest "message to whiterun", and when I go to Legate Quentin Cipius all he says is "keep your eye out for trouble, its only a matter of time. He is supposed to be telling me to meet up with Rikke. I have watched videos on youtube about this mission.

Any advice? I cant do the main missions now? I think if you cant even do the main missions then its kind of game breaking no? Help!!
