Where do you install your content? If you're on a Windows maching that runs anything greater than XP your content folders cannot be inside the program folder because Vista, Windows 7 and Windows 8 write protect those program folders. They should be installed to your Documents folder (there are options when installing Poser). You also need to give Poser local network access. If you're running a software firewall, you'll need to let Poser thru it.
