Also having issues since I started the Dawnguard campaign. 1) I go to fort Dawnguard and after he gives me the crossbow when I or the other npc recruit go to fire it nothing happens, my character twitches but that's about it. I figured no bigs I'm planning on going Vampire anyhow who needs the stupid crossbow anyhow. which leads me to the second problem.... 2) I save the Vamp chick, go see Daddy Vamp he transforms and bites me, but then I wake up in the other room and nothing happens.....The Vamp Cattle npc is there, as is Daddy Vamp, and my quest shows that I have to talk with him, but everytime I go to start the conversation he just turns and looks at me.. thats it, no dialogue. On the bright side I guess I'm a little less bugged than the others just getting his Yeargggg scream and nothing else. But I'm guessing there is some kind of bug in the script causing this issue.
