I've come across this problem myself when there are issues with certain fonts inside the PDF document. Are you in a position to re-make the PDF but with different fonts? Another alternative might be to look at converting the fonts to outlines within the preflight of Acrobat 9 Professional and then try re-converting once again.
Hope this helps and let us know how you get on ...
All the best,
