Merge a PDF with other files in PDFCreator

I have been
able to successfully merge two files into a single PDF using a VBA Module. I
have not been able to Merge an Excel file with an existing PDF...the pdf is the
second file added.  There is a control loop in the code

      
.cPrintFile (FILENAME)  'Add the PDF

       
Do Until pdfjob.cCountOfPrintjobs = 2

            DoEvents

        Loop

The PDF file
never gets added so the loop never gets exited.  I am wondering if I need
a PDFArchitect or PDFArchitect Pro to make this work.

Using
PDFCreator 1.7.2 on Windows 7.0 Pro 64Bit

Thanks
