I was found by the cutlists and i killed them and i have the orders in my inventory. Now i can read it but it wont let me continue the quest line like i want to. PLEASE can someone help me out?

I play on ps3 and i know that things like this happen just can anyone explain to me what is going on?

It requires that your character have started "The Horn of Jurgen Windcaller" for the Greybeards in order to be triggered.
