kmplot doesn't start

[Alessandro]

Hi all,
when I try to lunch kmplot, either from the kmenu or from a shell, start
with an error:
Could not find KmPlot's part, then appear a little window on my
desktop just with the logo and the application name but there aren't
menus,toolbars, icons and so on.
So I have try to find something in config.kcfg. There is a file:
'kmplot.kcfg' that seems to find out a configuration file: ' kmplotrc'
but this file is not present in my filesystem.

What I have to do?

Please help me.
Thanks

Alessandro
