Does anyone else get this message from recipients using Digital signatures?

Anybody else have this problem?  I have other forms that work just fine,

The attached file contains data that was entered into a form. It is not the form itself.

The recipient of this data file should save it locally with a unique name. Adobe Acrobat Professional 7 or later can process this data by importing it back into the blank form or creating a spreadsheet from several data files. See Help in Adobe Acrobat Professional 7 or later for more details.
