Poser isn't 'freezing' per se. That's the behavior it exhibits when it can't find something. It looks over and over again and again sometimes forever. I suspect the problem has to do with the libraries and where/which runtime the Pose files were installed. Those who install Vicky 3 to Poser 5 runtime and do the injections from Poser 5 runtime don't seem to have a problem. FWIW
