... I doubt it that its the actual perl file being the problem ..., however i have recently changed the pdf ...

Right, I too don't think the problem is with your Perl script. I suppose it's something with the PDF, however. Either it's been garbled for some reason, or Adobe InDesign introduced some feature that PDF::API2 can't handle...   Well, feel free to send me the PDF file (exactly as you have it on the webserver - preferably compute an md5sum too, so I can verify we have the identical file...), and I'll take a look... (I'll /msg you my email).
