I have just installed the mod Great House Dagoth by The Mad God. I got problems at the very beginning.

After I got infected by corprus, that's what I understood, I should wait for couple of days until I am transformed into a corprus creature. And then I can join in the Six House. Correct?

And I waited till it told me I am transformed. I can't see anything now the scene is all black, and I cannot even move. I tried to walk but I am just stuck there. But I can still right click to active the menu and stuff. I don't know what happened. Is there anything I am doing wrong or it is a bug? I hope someone can help me to solve the problem. Thank you.
