I finished the main questline with the vampires. Then i had myself cured becaue the negative effects outweigjted the positive imo, but now i am unable to recieve radiant quests from the vampires, or even complete ones i didnt finish during my time as a vampire.

So now am a able to recieve qiest from the Dawnguard, or am i blocked from doing any quests?

Anybody?

You join the vampires, anything involving the dawnguard is blocked for you.
