I have created two forms in LiveCycle Designer ES4. I want people to complete them using Acrobat Reader XI so I opened each one in Acrobat Professional XI and saved them with extended features enabled. I then tested them in Acrobat Reader XI before distributing them and found that one worked perfectly whereas the other form generated a message in Acrobat Reader which said: The document enabled extended features in Acrobat Reader. The document has been changed since it was created and use of extended features is no longer available. Well I haven't changed the document at all. I went from LiveCycle to Acrobat Professional to Acrobat reader. Why do I get this message and how can I get my form to work?
