PDFCreator Free Not Automatically Picking up files from Spool

I have installed PDFCreator Free v5.3.1. I am trying to run an automatic conversion and set the automatic flag, filename as DateTime, and File path. The file path has good permissions.

I run a print test page form the windows PDFCreator printer properties dialog and it works fine. I print from my application, the PDFCreator printer and it will populate the spool, but disappears without the conversion.

It seems PDFCreator may not be able to extract the file from the spool.

Is there a setting or priviledge on the C drive to allow this to work?

Any other suggestions?
