The usual freebie problem, the file has an absolute path to a texture file.

Open the file in a text editor (e.g. WordPad) and search for "F:model startInterior" and remove each occurence if you have the texture in the same folder as the PZ3.
Otherwise put the texture ("tv screen.jpg") into your main Runtime's textures folder and replace with ":Runtime:textures:"

Rendering in Poser might not get you the same result as what's shown on the download website, cos that was probably rendered in 3DS Max, and it's unlikely that the more advanced settings will have been replicated in the Poser setup.
