I added a date picker widget to my acroform created in Acrobat 9 pro. One user opens the form adds some info and emails to a second user. When the second user opens the form the following message began to appear after adding the date picker widget.
"This document contained certain rights to enable special features in Adobe Reader. The document has been changed since ti wsa creatred and these rights are no longer valid. Please contact the autheor for the original version of this docuemnt."
Is there a setting or something I need to configure to use the date picker widget in reader or a way to disable this message?
