PDF does not print (Ghostscript *** Could not open temporary file ***)

I recently installed PDF Creator 1.7.1 on my computer, put can not get it to print to PDF.  When I try to print a test page, I see a *.inf file shown in the print monitor and a *.inf and *.ps file show up in the temp directory ...\\AppData\\Local\\Temp\\PDFCreator\\Spool.  As soon as I click save, the files in the temp diretory are deleted, but the PDF file is not created.  I previously had PDF995 installed, but it had stopped working.  I don't know if that was related to my current problem.  I have included the log file below.  Any suggestions how to fix this?  I have unstalled and reinstalled a couple of times, with no change in behaviour.
