I do appreciate your taking the time to help me. I was able to get Prima down to 58 once, but then Flavens shot right up to 270 and I lost everyone. I'll keep trying because I really do enjoy the game and I want to read more of the story. Thanks.
I downloaded 1.76 yesterday, installed it today...I was very pleasantly surprised that I was still able to load my saved games. It still took a few tries, but Jason, Louis and David finally defeated the three sisters! Took a few tries, but Jason and Blu defeated them, too! Now Ryu keeps getting slaughtered by them. I'll keep trying. Thanks for responding. I do feel at least a little better now that I've seen comments from other people having the same problem, at least it isn't just me.
