problem with powerdot package with Miktex 2.9

I have used powerdot with MikTex 2.8, no problems.  Now I have
upgraded to MikTex 2.9, and when there's a list, it fails to compile.
Works OK as long as there are no list environments.

Minimal example:

\documentclass[style=simple]{powerdot}
\begin{document}
\begin{slide}{}
Hello
\begin{itemize}
\item world
\end{itemize}
\end{slide}
\end{document}

I compile using latex - dvips - ps2pdf - view pdf
It fails with error message:

! Undefined control sequence.
<argument> enit@cw@\@enumctr
l.12 \end{slide}
The control sequence at the end of the top line
of your error message was never \def'ed.

I asked about this on the powerdot mailing list, another user said it
worked for him using the "sailor" style in powerdot but not with the
"simple" style.  For me, it fails with the "sailor" style too.

Any help wd be appreciated.
