That bottom folder entitled Runtime is "illegal" and can cause problems down later.  Your best bet is to completely uninstall P12 and delete all your content including all related folders.  Reinstall everything.  For the additional content, you need to go to Posersoftware.com and with your validated license access the section that contents the legacy files.  I see that you did not link your Poser 11 Content to Poser 12.
