Xbox 360:
Some people were having problems with Dawnguard when it was released. This bug is kind of weird but its easily fixable. If you download Dawnguard and it keeps kicking you offline when you attempt to play Skyrim this is what you do:
- Delete all things that are corrupted on your Hard-drive/Memory Unit
- Clear system cache twice
- Then you have to recover your account and start up Dawnguard
After you do that you should be allowed to play online again and you'll be allowed to enjoy Dawnguard!
This quest may be impossible to start as Aela will constantly give the player Animal Extermination quests, this is possibly caused by marrying her. May also be caused by being cured of Lycanthropy. Possible solutions below:
Have all the remaining witches heads in your inventory and not stored in one of your houses
One possible way would be to stop following the Totems of Hiricine quest and follow a quest that leads the Dragonborn to an area that Aela cannot follow you into, thereby forcing her to leave your side and put the quest on hold. Afterward, find her and (SAVE FIRST) start the quest again and see if the Totem will be at a different location, or get her to follow into Haemar's Shame, THEN start the quest again.
If any of the Companions died (apart from Kodlak) before this quest, Aela will constantly talk to you when she gets close enough. This also makes her follow you everywhere and counts her as a pursuing enemy.
- Solution: Pay all bounties in all nine holds, but do not go to jail.
