I recently bought the dlcs and started a new character. I'm level 27 and after downloading the Hearthfire and other DLCs I tried to complete the Walking Nightmare quest so that I can purchase land in Dawnstar. But if I try to save in the temple the game freezes and if I try to complete the quest without saving it will also freeze. If someone knows what to do I would just love you! I have been waiting to play these forever!

unfortunately this quest was bugged from the beginning and it was made worse with the new update. You'll have to make it though without saving. I gave up at the end as I was unable to get the staff and couldn't stop the mage from attacking me.
