This should work for you, I use it all the time. http://skyrim.nexusmods.com/mods/20394

http://skyrim.nexusmods.com/mods/21639 I've seen this been created, haven't tested if it works though. Maybe it'd help ya?

Mmm, this problem happened to me with one of my other saves, though I did have the vampire blood before the update. I think that's the main problem as the update probably would have changed the features of becoming a vampire and etc. I think this mostly because standing feed was added in for vampire lords and etc. The only way I see to solve this is creating a character and console command level it up to ten and see if this bug is still continuing.

Okay first thing first, even though this should solve most of the problems concerning doing the quests, it will not fix the bug where you are unable to do anything in your vampire lord form, and also if you do turn into a vampire lord if you have that bug that unable you to do anything, it WILL revert you back to a mortal for some unknown reason. I couldn't find the cause of this, but i'm not really a tech wiz. When you are changed into a vampire lord for the first time, you are changed into a mortal by chance. If this happens, after you revert, you need to open console commands and type in " setplayerrace [race]racevampire" where race would be replaced by your current race. Be aware, that the problem concerning vampires could be caused by you using a custom race. Sorry if this doesn't help you though if you have the same problems :c
