Were the installs of Ghostscript and Scribus made just after a clean boot? If not, then I would suggest uninstalling both, then rebooting and - at the risk of sounding paranoid or overly persnicketty - I'd install Ghostscript, then reboot, then install Scribus.
And criticizing "Windows Classic" could be the curse of it all ;) [I hate all that newfangled XP stuff] Barry
