I'd run into this problem with Poser, and several other programs such as MS Word and Adobe PhotoShop. The problem was actually caused because I insisted on turning my wife's computer off while she was out of town for two weeks. Our printer was hooked up to my wife's computer, and these programs would not load because they couldn't find the printer on my wife's computer. There are a few easy solutions: 1.) Never turn off the computer that has the printer hooked up to it. 2.) Get a cheap printer for each computer on the network. 3.) Buy a printer server. The printer(s) would be hooked up to this device, and you would never turn off the server.
