Hi,

We are experiencing problems with a PDF file that is giving our clients a message that says 'File is corrupted.' What is odd, is that we can't recreate this problem on any of our computers, nor can any friends or associates. We try to create the exact same scenario's as our clients (for example they don't have full version of acrobat, just the reader. They are accessing from with a government firewall).

Right now, I don't have a file to attach for you as an example.

I see from former messages, that this might indicate a problem with xref or that that [technical term] is offset. I see that some of you have looked at the xref from a file and have determined that its messed up. How do you do this? I see how to get this info, but don't see how to see if it's messed up.

If it is determined that the xref is messed up, how do you fix it? Is there a setting on my batch processes, etc that I could set to prevent this from occurring? How does the xref get messed up in the first place?

Right now, our current workflow is to run 2 batches on all our PDFs in order to create generic PDFs that are all at the same settings.
- Our first batch runs and sets each PDF back to Acrobat Version 6.0, optimizes for the web, etc.
- Our second batch, is with PDF Enhancer program, and overall optimizes the PDFs.

Other info about our pdfs:
- We tag all PDFs.
- We receive PDFs from outside vendors, some are developed internally, and PDFs are developed from all sorts of programs.

For the most part, this process has worked perfectly. For some reason, however we are getting messages from clients that the files say 'File is corrupted.' And, we are trying to figure out a way to prevent this from occurring in the first place.

Could you give me some advice as how to troubleshoot this issue?

Thanks in Advance!
