Troubles with joing one of the Clans (possible spoiler)

[The Chosen One]

Omg, long time no see folks...

Well anyway - here I am with my problems. The current problem follows:
I want to join the Clan Aundae; I found their hideout, and their leader, Dhaunayne. The tricky part is that I can't get her talk about "her family" and therefore I can't trigger the first quest for the Clan and join it. What's the problem?

I read that you can add topics in the command console, but I don't know a)the code b) how to type it c) and when %)

Ehm...help me plz?

You have to become a vampire by being bitten by one of the clan to join the clan.

Ehm and how do you become bitten then? I've entered their HQ once more and let numerous vamps attack me, but nothing happend - they just stroke upon me with spells and weapons.

You have to catch a disease while fighting them and then wait 3 days.
