Which DLC? Which locations? (Some don't appear until you accept a side quest, or talk to certain NPCs.)
Oh, seems I forgot the main relevant parts. Warden's keep and The stone prisoner. It's been a while since I played DAO, but as I recall it, the Stone prisoner should add a location on the west side of the map after Lothering when you can move around freely. Not quite as sure about the keep,.but I thought that would start maybe in party camp.
I have a similar problem, in that the DLC does not appear in game. That is, it does not show up as Available, Downloading or Installed Content. I've followed the steps mentioned in the posts above and unfortunately nothing has been resolved.
I also have the same problem when logging in while in the game - it says the user name and password are incorrect, but shows me logged in on the lower left hand corner :/
I would also really appreciate any help on this matter.
