Hi,
this seems to be a problem of the latest Ghostscript version 8.71 coming with PDFCreator.
Please go to
sourceforge.net/projects/ghostscript/
and download the previous version 8.70. You can use this link
downloads.sourceforge.net/project/ghostscript/GPL%20Ghostscript/8.70/gs870w32.exe
After the isntallation choose Ghostscript 8.70 from the PDFCreator options and test it again.
Best regards,
