I'm wondering now if I caused problems with the P7 runtime by copying and pasting it from a backup drive when I got this new computer. I say this because I then encountered several problems with the P7 library using Poser 7 for the first time, and several files had lost their links. So I then ran the utility Runtime Repair to try and fix those problems, which it did. But when I acquired Poser 8 I found that the P8 library couldn't identify the old rsr pictures files, so I ran Runtime Repair again to convert all the rsr's to png's, and that was fine. But that also seemed to be when I first noticed that the P8 library was starting to crash. Does that help this issue?
