I found it very very easy to fry the HIP controllers when things went wrong. Have you checked to see if they are getting hot (or your FETs) ?
I finally managed to get mine going with the last 2 I had knocking around before I fried those as well by accident and went for a P channel high side using transistors in the end.
Not as nice but a bit more robust.
