Error during signature verification. Can't verify signature.

I'm trying to validate a signature for a pdf file.

When I open the document a banner "At least one signature is invalid" with a signature panel button appears. (Refer to figure 1.)

When I open the signature panel and right click on the signature "Rev.1: Signed by Preflight Ticket Signature" and click "validate signature"

the error message appears (figure 2)

When I click "ok" another error message appears (figure 3).

How do I fix this problem?

This looks like an Enfocus (PitStop) problem. You should open a ticket with them. Invalid byte ranges imply that the file was not saved correctly during signing.

Yo man same here, ever since Adobe updated I have not been allowed to make notes in my PDF because it says the signature does not give me authorization, however, for the past year I have been able to type text boxes, highlight and mark my pdf for notes. I've never had a problem with signatures or editing a document before. I look at the signatures and see "Rev. 1: Signed By Preflight Ticket Signature. It will not let me validate it or change it. I have a board exam coming up and need to take notes. How do I get rid of this?
