PDFCreatoe 1.0.2 rinning as a service on Windows 2008

I've installed PDFCreator 1.0.2 on my Windows SBS 2008 server in server mode & have attempted to configure it to run as a service.  I've followed the procedure outlined in slipaway's post at http://www.pdfforge.org/forum/help/5145-windows-server-2008-installation-problems, which seems to be a consesus of most of the other posts on the subject, but I'm still having issues.  Everything seems to have installed ok & there are no errors, but when I start the PDFCreator service it stops immediately with the standard "Some services stop automatically if they are not in use ..." message.

I'd be very grateful for any help on this.
