Yes, there is an issue with PDF files greater then version 1.4, I am looking into this, I have some example files that I am using at this moment. (You can find the version by dropping the PDF-file into a normal text-editor (e.g NotePad) and look at the first characters, they are something like "%PDF-1.4").
What is the version number of the file that gives the problems?
