When I start a new game and try to choose to go with Hadvar or Ralof after entering either keep doors the characters don't come with me to cut my bounds. The quest doesn't activate enter the keep either. Is there any way to get around this? I tried disabling dawnguard and reinstalling but it just wont work. I have no other saves to go off because I reformatted and didn't really want to save my old saves because I wanted to start fresh.
