Got 'em. I reloaded them fresh into their own runtime on the desktop and they worked (eventually). V4 wasn't working properly before I upgraded, and I realized that her file that was stored in the DAZ Install Manager was messed up - actually missing stuff. I reloaded V4 from the DAZ account and she's complete now.

DAZ has redone their account screen setup, and it's a lot easier to get to old downloads now.

Thanks, everyone!!
