Probably the message is something like this: "Insufficient disk space to render at this resolution." The first question, as already stated, is how much free hard drive space do you have? You might just try defragging your hard drive first to see if that fixes the problem. If you free space is sufficient, then there are two fixes: 1.) Adjust your swap file settings (I never do this) 2.) Place your Poser installation on a different hard drive than Windows. That usually works for me. If you've done this, and still get this message, then defrag your hard drive.
