If you ever have had this bug where your hp will not load in the MPE, it may be because you have a 0 (zero) in the HP for one of the tac icons. In this case, I had a romulan HP fail as a result of having zero marked in the lock icon (the transparent icon that shows up when a target is in the arc of a given weapon) and in this case it was a pulse weapon. Once I changed that, it worked. Just so ya know...
