Koma-script letter error

[Walter van Holst]

Hi all,

When trying to use the Koma-script Letter template I get this error:\

! LaTeX Error: \begin{letter} on input line 27 ended by \end{document}.

 \end{document}

Your command was ignored.
Type  I <command> <return>  to replace it with another command,
or  <return>  to continue without it.

Suggestions on how to deal with this would be most welcome.

Regards,

 Walter
