i too am having the same issues. there's some incompatibility issues with some of my mods and my characters where suck in first person. I have removed dawnguard but how do you re down load? Im going to try to verify the game cache and see if that with re install the dlc. "edit" So you go to the page of the dlc and click the already own play now button. it will be green and its will start the download process.
