I had the following problem with Caris and desparately look for a solution. Because Caris, after
a bit of touch up, is a beautiful athletic, good looking model. Much alike the Jessi character in P6.
I was almost ready with the figure and when I wanted to add a hair set (Felicity Hair) then whole thing crashed.
Now the funny thing is the original body morph doesn't work anymore. Even after removing the
old file and reïnstalling the basic one. No nothing.
Frankly speaking, 80% of the hairstes in the freezone doesn't work. I use Poser 7, the latest version, it might be that artists are supplying items for older programs. I don't really know  why
your program crashed and why it cannot return to 0 state when reïnstalled.
