[pdftex] PDFSlide not generating output

[Alexander Celle T.]

Hi, I wanted to make slides for PDF presentations but I'm having
problems with pdfslide.

I am using the latest release of Miktex (2.1) with the pdfslide package
it includes.

The sample file I'm using is:
%%%%%%%%%%%%%%
\documentclass{article}
\usepackage[latin1]{inputenc}
\usepackage[spanish,english]{babel}
\usepackage{pdfslide}
\begin{document}
\section{first}
first
\section{second}
second
\end{document}
%%%%%%%%%%%%%%
And the  final part of my log file is:

%%%%%%%%%%%%%%
(C:\texmf\tex\context\base\supp-pdf.tex
(C:\texmf\tex\context\base\supp-mis.tex
loading : Context Support Macros / Missing
\protectiondepth=\count97
\scratchcounter=\count98
\scratchdimen=\dimen119
\scratchskip=\skip50
\scratchmuskip=\muskip11
\scratchbox=\box28
\scratchread=\read2
\scratchwrite=\write5
\nextbox=\box29
\nextdepth=\dimen120
\everyline=\toks32
\!!counta=\count99
\!!countb=\count100
\recursecounter=\count101
! TeX capacity exceeded, sorry [input stack size=1000].
>->\active at prefix >
                   \normal at char>
l.465 \protect

If you really absolutely need more capacity,
you can ask a wizard to enlarge me.

No pages of output.
%%%%%%%%%%%%%%%

However, if I take the \usepackage{pdfslide} declaration out everything
works fine and I get a normal article output.

What can be wrong?
Thanks, Alexander
