Didn't notice that (hadn't tried loading it).
That file comes with Poser6, so if your using an earlier version it probably doesn't exist.

To get the file to load replace the filename (including the quotes) with NO_MAP or change the path to that of some other reflection map that you do have (e.g. "Runtime:Reflection Maps:SilverRefl.jpg" or "Runtime:Reflection Maps:SilverRefl.pct" as one of these comes with Poser back to at least P3) .
