The updater loads all files from here:
http://laanx.fragnetics.com/updater_hiddenUser: psteam

There you will find a file called: updater1023.zip
You can download this and extract the contents to your planeshift directory.
After that you can do the \"updater.exe --auto\" stuff from a DOS-window, this worked for me ( even on Win98 ).
If this wont help... give more information about your system/errors:
- which windows are you using (Win 98, Win ME)?
- which error message do you receive running the updater-beast with --auto
