    Adobe Signature Invalid - What Gives???

    Buzz81 Level 1

      I am trying to digitally sign forms for an application.   I click Advanced, Sign and Certify, and sign the document like I always have.  However, after signining, a grey box pops up that says "There was an error when attempting to commit this signature.  The document was not saved.  The file may be read-only, or another user may have it open.  Please save the document with a different name or in a different folder."   However, I am saving the doc as a different  name alreay, and it's not read only or open by someone  else. 


      When I close and reopen the document, the document is digitally signed and the signature looks like it always has.  However, at the top of the page, there is a a blue signature panel that says "at least one signature is invalid."  When I click the signature panel there is an option to "Validate All."   However, when I click it, nothing happens.


      How do I fix this?   I'm using Acrobat Pro 9 on Windows 8.1
