pdfPrint wPDFViewDemo03.dll won't accept file name

I am trying to use the demo for pdfPrint and no mater how I send the filename parameter wPDFView always takes the first character of my parameter and appends it to the application path and then fails...

For example I call this:

pdfPrint('NFA_Letter.pdf', '', '', '', 0, '');

And get the error
'c:\my\app\path\N' not found.

Thanks for any assistance,
Tony

I thought moving to the live version might solve this so I went ahead and purchased it. Now I have a different problem...

When I call pdfPrint using these credentials I get an error code -1.

Here is my code (PDFFile is a string with the file path/name and Options is a string with options):

Testvar := pdfPrint(PChar(PDFFile), '',
PChar('Anthony Niemann'), PChar('L***************2'), 1*****0,
PChar(Options));

I am using RAD Studio 2009.

What am I doing wrong?

Thanks,
Tony
