Updated PSTricks problem

Hi ... I downloaded the latest PSTricks files and suddenly prosper and
HAprosper give error messages I don't understand.

My minimal file is:

\documentclass[pdf,colorBG,slideColor,autumn]{prosper}

\begin{document}

\begin{slide}{Test}
This is a test
\end{slide}

\end{document}

The extract from the Latex error message is as follows (and seems to
occur with any style except plain .. which does however work OK):

........ (C:\localtexmf\tex\latex\pstricks\pstricks.sty
(C:\localtexmf\tex\latex\addpack\xcolor.sty
(C:\texmf\tex\latex\00miktex\color.cfg)
(C:\texmf\tex\latex\graphics\color.sty
(C:\texmf\tex\latex\00miktex\color.cfg)

! LaTeX Error: Missing \begin{document}.

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

l.159 \definecolor{black}{gray}{0}

?
! Emergency stop.
...

l.159 \definecolor{black}{gray}{0}

It seems like I've lost a file, or have an outdated file?? Any help?
