I have a rather large pdf document, 62,025 KB, that I have been trying to insert both a header and footer on each of the 9,912 pages with no luck. Most often the document freezes up and Adobe will say that it is "Not Responding". Or I get an error message that states "An error was encountered while retrieving page content." I have to deliver this to a client with their specifications to include a header and footer with their identified text, but seem unable to do so. Help, please!
