Moving this discussion to the Security & Electronic Signatures forum.
I doubt that you can no longer create a digital signature just because you updated Acrobat, but rather it's because the digital ID that you use to create the digital signatures has expired. If you look in the Security Settings dialog and select Digital IDs from the tree view you can see the expiration date of the digital ID.
