My screw-up was in buying a bug-fix.  :-)  Should've researched more, at least here in the forums.  I would have seen the trouble ahead.

I "think" my install was fine.  All the new content appears to be in it's proper places.  I really LOVE the new one, but I can't import anything I've tried (Was trying to do a figure I put together in DAZ3, but every time I tried to import the figure, it crashed).  I even did some older, plain figures I had left from past scenes I made that I know were not a problem and it still crashed 6.3...  And the render times are horrendous!  I would guess that they are nearly twice as long as 5.5...

The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!' (I found it!) but 'That's funny ...'
