I just downloaded Dawnguard and noticed that most of the new animations dont work. For example anyone tries to take out a crossbow their character just goes into the "default stance" you know when your arms and legs are both spread out slightly, and no movement at all, people just start gliding on the floor. Sometimes however it does work, I tried switching back and forth between weapons and for a few seconds I saw the idle crossbow animation, but then I moved forward and back to the default stance.

***SPOILER***

Also a bit later during the first quest when you have to touch the pillar, the camera started to pan out to 3rd person but all I saw was my char go back to the default stance and then the camera couldn't seem to decide if it wanted to be in 1st or 3rd person. The last thing I noticed before I stopped playing was that the mysterious woman holding the elder scroll had an idle animation that also caused her to go to the default stance during our conversation.

Anyone have any fixes?
