You're using relative paths. Are you sure that they are pointing to the
correct files?

Is it actually generating the PDF?

You might think that when it generates the PDF it overwrites any
existing file of that name but is it? Is it simply giving you the PDF
that's already there?

Experience varies directly with equipment ruined.
