Hello, I can't launch the menagerie or higher levels of the reckoning for some reason even though I have done all the quests and own the dlc.
For the Menag, you have to play throught the entire Forsaken quest line (including the first Dreaming city mission) as well as the quest line Calus' robot gives you; up to fixing and placing a rune in the chalice. This has to be done on EVERY character that wants acces to the Menag/Raid.
You need to be 680 for T3 reckoning, and 690 for the Menagerie. From your profile, I see that you are 669. You should have received a bunch of 690 gear when you completed the Invitation quest from Benedict.
