Cannot edit with Camera Raw from Bridge

I am no longer able to edit photos using Camera Raw as of a few days ago. When I select photos within Bridge and click edit in Camera Raw, I get the spinning icon, a small window then opens and closes quickly and Bridge freezes without opening Camera Raw. It shows using over 50% of my memory in task manager, and stays locked up and the only way out is to end task. I have attempted to re-install prior versions all the way back to 12.0.4 all with the same result. I have attempted both software and hardware encoding with no impact. Anyone else having similar issues or ideas?
