Problem with plotting HPGL file from OSD

Hi All, I plotted my drawing to a plot file using HPGL/2 plotter (test.plt). When I insert the file into word using the HPGL (*.hgl;*.plt) filter, I got an "empty" drawing or picture. I have also changed the lines color to be something else other than white to avoid inserting an "empty" drawing. Does anybody face this problem before?
