[pstricks] HA-Prosper - xcolor - pstricks-add

[Christophe Jorssen]

Hello,

I'm trying to use pstricks-add with haprosper, but it seems not to work.
When I add \usepackage{pstricks-add} to HAPIntroduction.tex (included in
HAprosper distribution),

%%%%%%%%%%%%%%%%%%
\listfiles
\documentclass[pdf]{prosper}

%================================================

\usepackage{pstricks-add}

\usepackage[toc,highlight,HA]{HA-prosper}
%%%%%%%%%%%%%%%%%%%%%%%%

I get an error message related to some color definition :

! LaTeX Error: Missing \begin{document}.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.

The listfiles is (I think I'm up to date ?). Can somebody help me? Thank you
in advance

Christophe
