Unable to use signature I created several years ago. Certificate says it expired 2/14/16. I upgraded to IE 11 2/13/16, not sure if that is the issue. Cannot create new signature since it continues to go back to my old signature. How can I fix? Several documents I need to sign and send.
Had you procured your signing certificate from a Certificate Authority (CA) or created a self-signed certificate. In either case signing certificates have an expiration date after which they cannot be used. Some CAs issue certificates that are good for a year or two. If you procured your signing certificate from a CA you need to get a new one from them. Self-signed signing certificates that you create in Acrobat are good for 5 years. If this is how you got yours you need to create a new one yourself.
Have tried to create a new signature, but Acrobat continues to go to old certificate.
In the "Sign" dialog click on the "Sign As" field (not the words) where the certificate is displayed, and you'll get a drop-down list which should contain your new certificate. Select it for signing and it should appear by the default the next time you sign.
