[pstricks] Problems with pstricks-add 2.73

[Boris Veytsman]

Greetings

I've tried to upgrade pstricks-add from 2.18 to 2.73.  Unfortunately,
the new style seem not to work.

Here is a test file (test.tex)

------------------------------------------------------------
\documentclass{article}
\listfiles
\usepackage{pstricks}
\usepackage{pst-math}
\usepackage{pstricks-add}

\begin{document}
\begin{center}
    \psset{xAxisLabel=$x/w$, yAxisLabel=$\Delta E/E_d$, Dx=1, Dy=0.5}
    \begin{psgraph}[arrows=->](0,-1.5)(3.5,0.7){10cm}{4cm}
      \psset{plotpoints=500}
      \psplot[algebraic=true, linewidth=2pt]{0.0000}{3.5}{-EXP(-x)}
    \end{psgraph}
\end{center}

\end{document}
----------------------------------------------------------------

I latex'ed it and got the following file list:

 *File List*

Then I dvips'ed it:

but whenever I try to see it, I get:

Here is the pstricks.pro used:

%!
% PostScript prologue for pstricks.tex.
% Version 1.00, 2005/09/18
% For distribution, see pstricks.tex.

Note that there is no problem with the old 2.18 version of pstricks-add.

Good luck
