Physics Results Explorer not running

I am having the same problem as I did yesterday at this same time that even though my Simulia simulation runs, I cannot get Physics Results Explorer to run.   It was running earlier in the day but now just locks up my simulation when I try to load it and review my results and have to do Task Manager end task to get back into the platform.   I reopened my sim and the same problem repeated  I also tried to launch PRE directly from the compass and it still hasn't loaded after waiting over 20  minutes.

Is anyone else having this problem......how to resolve?
