Importing PDF files corrupts current document

[tejas10]

We have a problem with PDF files from one vendor in China. We receive PDF docs from them via email. When we insert the docs into a previously created PDF document and then save the document, the entire doc is corrupted when re-opened. Both the imported doc and the rest of the previous pages are messed up. Characters are missing and others are in apparently random places.

When we create our own PDF files from their emails it is not a problem until we insert one of theirs. We can add PDF files we created into the main doc repeatedly with no problem.

The PDF's they send are invoices with some grpahics. Interestingly, if I open a PDF file from them, insert another PDF from them, then save and re-open, there is no corruption. Only combining their PDFs with our creates the problem. Anyone got any ideas?

First thing I would check is what version of PDF are they making e.g. 1.3, 1.4? (not the same as the version of Distiller). If you open a PDF in Notepad, it will say in the first line what version it is. There may just be some sort of incompatibility here between PDF versions.

Next thing is to find out what program they are making them from and how.
