For the library, some people have reported that just restarting Poser fixed that. Others needed to turn on the refresh on launch. Edit>gereral preferences library tab check the box for refresh on launch.

I haven't updated yet myself, but in the last update, I remember that the first load or two of the library took a while to show. I don't know if that's the case here, but you may also just need a little patience.
