My workflow uses FM10 and Acrobat Pro to create .pdfs for sending out to clients. Just had a 'phone call from someone saying he can't open the .pdfs any more, even though he's been using them for a while. Acrobat Pro X brings up the bookmarks list, but then displays the message "There was an error processing this page. There was a problem reading this document (109)."
Any idea where the problem lies and what to do about it? I suspect it may be file-corruption at the client's end, but I'd welcome confirmation before telling him so!
Did you send these PDFs by e-mail? If so, did you check to be sure they were encoded? Sometimes e-mail clients see PDFs as text and they are not, they are binary. A few years ago there were also issues with Outlook treating PDFs incorrectly, even if properly sent. I don't remember the details on that one.
Chances are, if you are seeing error 109 when opening a PDF file, the file is corrupt. If you downloaded the file, try downloading it again. If you created the file yourself, try creating it again from the original source. That may be all you need to do to solve this problem.
On the other hand, there may be nothing wrong with the file itself, but your PDF reader may be having trouble making sense of it:
Given the client has been using the files quite happily for a while and now reports a problem, I think we can discount transmission problems and problems with the reader … sounds like corruption to me. I've already sent the client a new copy, which seems to behave as required. I'll advise them against trying to meddle :-}
