I have created a form with a pdf background that is stored on a shared server. Most users access the form with Adobe Reader X. When originally created, the feature to enable usage rights in Adobe Reader were enabled. I updated the form to correct the text length allowed in a particular field. Now when you access the form via Reader X, the following error message appears and the form no longer works. This does not occur if the form is opened in Acrobat Professional or Standard, but most users have Reader X. Can anyone please help?
You lose the extended features on a PDF any time you modify a PDF with Livecycle.
After modifying your PDF with Livecycle you open it again with Adobe Pro X and save this PDF as a Reader Extended PDF.
