Okay, I (and by I, I mean someone else told me) figured it out. If you are at an area that's within the DLC, leave and go somewhere else (such as whiterun, or whatever). Save your file, and exit the game. When you're opening the game back up, go to Data Files and disable the Dawnguard DLC. Open the game back up, and re-save. Close the game, Re-enable dawnguard, and start the questline over again. This should fix the problem, at least it did for me!
