One thing I read about biting (and I don't know how much it applies to you) is that when they do bite, especially when you are playing, and they bite hard, you need to say "ouch" and walk away. Basically that's what other dogs would do if they are playing with them (like their siblings) and they will know that if they bite, "good thing"=you playing with them ends. And if they don't want "good thing" to end, and usually they don't, they will slowly understand not to bite. Maybe start with practicing that and slowly she will learn not to bite you at all!
Good luck!
