I keep getting the silent treatment, and was hoping you folks could help me know when to expect her to talk.

After I did her first companion quest, she didn't speak to me until after completing Chapter 1, which had enough affection to get her to give me the "Freedom" quest where I freed her sister. I did that, and now am level 38, on Taris, in Chapter 2.

Where do I need to go/what level do I need to be/how far do I need to progress/what level affection to continue the story with her?
