Okay, I'm running Windows 8.1 (not 8.13), and the version of Poser 10 that I have is 10.0.3.26066 (without the update) which means I don't need the update, I'm guessing.

 When Windows 8.1 came out my Poser 8 stopped working, and I was told that Poser 10 would work with the new Windows version. Everything else looks good, but just no libraries. Sometimes I get the "Add Libraries" button to show (after re-opening P10 a few times), but it doesn't work, and most of the time the entire Libraries area is empty.
