My case is quite similar to yours. I've got the first rejection from my safe school (which for me means that my application season is closed). But my POI is very nice and she commented on the application and encourage me to apply to anther MA program (and I might do that for my next application). According to her the problem was my writing sample. They were looking for a work demonstrating your ability to ask original research question, archive work and control of bibliography. (I used to be quite satisfy about the WS, which is a re-work of my MA essay).
But in your case there is still hope! It's not the end of the waiting game. (That's also what I am telling myself.) Somebody shared their successful stories in this post: it would be helpful for you.
Good luck to everyone
