So i made it to the twilight place, to return the key and jump down the hole. I listening to Nocturnal speak and when she finished talkin ......................nothing the quest book justs tells me to listen to her, which i did. I looked up the quest on youtube, and i know kaliha or whatever her name is suppose to talk to me but she doesn't appear for me. So is this just me or are others having this problem. and how do i fix it?

You need to speak to Karliah. There is a bug that Karliah is not present during the speach from Nocturnal, meaning the journal will not update properly. There are a couple of ways to resolve it;

1.) Try waiting for a few hours and Karliah may appear from the doorway.
2.) Load prior to dropping in the hole and make sure Karliah is present before speaking to Nocturnal.

The guide says she needs to be present for the whole speach, however this is not the case. She was only present in my game for 3 seconds before leaving just prior to me speaking to nocturnal. Waiting 2 hours after the speach she appeared and the quest triggered.
