In Adobe Acrobat 10.1.6, combinging several PDFs with the "Combine Files into PDF" is silently failing, by appending the PDFs together but deleting some form fields off at least one of the forms (usually the first one, which is the most complicated of the bunch).
The form the fields disappear from is the one I would like first in the combined PDF (call it A).
However, I tried an experiement where I insert A after another PDF using the pages tool. In that case an error shows itself as "an incorrect structure was found in the PDF file".
How do I repair the PDF file A so this doesn't ocurr? I tried repair acrobat, that did nothing to help.
