distiller problems

I am a brand new user of prosper (which I am sure I am going to enjoy). 
  I am running in a windows environment, I am using MikTeX version 2.1, 
propser.cls version 1.1.1.1, dvips version 5.84, gsview32 version 4.4.0, 
and distiller version 5.0.5.

Here is my preamble to the LaTeX file:

\documentclass[pdf,nototal,azure,slideColor,nocolorBG]{prosper}
\hypersetup{pdfpagemode=FullScreen}
\usepackage[T1]{fontenc}
\usepackage[latin1]{inputenc}
\usepackage{pstricks,pst-node,pst-text,pst-3d}
\usepackage{amsmath}
\usepackage{graphics}
\usepackage{epsfig,color}

\begin{document}
...
\end{document}


When I generate the .ps file, I can view it succfully with gsview32; I 
can also convert it to pdf format using the "convert" option using 
pdfwrite in gsview32, and can then view the resulting .pdf file using 
acrobat.  But when I run distiller on the .ps file, the job fails with 
the following message:
--

%%[ Warning: PostScript error. No PDF file produced. ] %%
Distill Time: 0 seconds (00:00:00)
**** End of Job ****

I am at a loss as to why this happens.  I would appreciate any help.
