Apparent issues with v1.7.2

Hi,
I have been using PDF Creator for a number of years, and have had no problems with updating through the various versions using the default settings during the install.

I am, however, seeing issues with v1.7.2.  All PDF's created are blank, about 3kb in size.  Reverting to v1.7.1 and retaining all settings produces the expected documents.

I am using Win7 Pro and MS Office 2010.

Thanks,

David
