after I finished the Dawnguard's questline two days ago, I asked Serana to turn me into a Vampire.
The only problem is that not a single Dawnguard member wants to talk to me anymore.

They say something like "Get away, monster!", or "As long as you are one of them, you are no longer welcome here".
Is there any way to fix this? Maybe the console? I'd like to stay a vampire lord, but I also want to be a member of the Dawnguard.
(Sorry for my bad english, i'm from germany)
