This is why I won't ever buy bindings from anyone but Backcountry. Snapped my bindings a few weeks ago and the returned them no problem. I know this doesn't help your problem, but good luck with the break and binding.
Adjusting the foward pressure may help but thats more pushing the boot foward. What he has is more like losing some of the DIN pad on the heel of the boot. Its a bit like a well worn out boot, you could set the foward pressure but there would still be alot of play.
