Save-able / fill-able file cannot be used
Hi,
I have created a from using a trial of Abobe Acrobat X and everything was fine and working well. Eventually we purchased Adobe Acrobat XI Pro (X was no longer available) and had to make changes to the form. I saved a copy, made the edits and then saved it as Other, Reader Extended PDF, Enable More Tools. I can fill and save the filled PDF using the Adobe XI free reader but my other users (using Adobe X on Vista) get an error saying "This document enabled extended features in Adobe Reader. The document has been changed since it was created an use of extended features in no longer available. Please contact the author for the original version of this document." Even on the original file that error comes up. I'm not sure what I'm doing wrong. Any insights?
