    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?
