[Tex/LaTex] PSTricks package giving xkeyval error

pst-optexppstricksxkeyval

I have been trying to solve this error by myself but did not find a way.
So if someone out there can help me, any help is greatly appreciated!

I use Texmaker to run MikTex 2.9.
I want to use the package PSTricks to draw something.

To do so, I run LaTex on an UTF8-formatted tex-file.
This is my minimal example:

\documentclass[11pt, a4paper]{scrbook}

%\usepackage{pst-all}
%\usepackage{pstricks}
\usepackage{pst-optexp}
%\usepackage{pst-all}
%\usepackage{pstricks-add}

\begin{document}

\begin{pspicture}[showgrid=true](4,2)
  \optdiode[conn=-i](0,1)(4,1){Diode}
\end{pspicture}

\end{document}

and it gives me an error message saying:

! Package xkeyval Error: 'conn' undefined in families `,pstricks,pst-node,pst-t
ools,pst-plot,pst-eucl,pst-3d,pstricks-add,optexp'.

See the xkeyval package documentation for explanation.
Type H for immediate help.

l.46 \optdiodeconn=-i(4,1){Diode}

There is no more an option conn in the current version (see documentation!) Use instead:

\begin{pspicture}[showgrid=true](4,2)
  \optdiode(0,1)(4,1){Diode}
  \drawbeam[beaminsidefirst]{}(B)
\end{pspicture}
