If the cert shows as revoked, then they probably need to get a new one.  This would have been revoked on the issuing CA and there isn't really a method of un-revoking the cert.  If it was suspended, it could be unsuspended but that's the best shot without reissuing, and suspending a cert is not common practice for most companies.

Try just opening up the cert without going through the app and make sure this is the case if you think it may be a bug with the software.  If it shows up as valid when viewing it directly, then please note that.  Another method is a bit of a pain usually, but you can also check the CRL (certificate revocation list) that is published regularly by the CA.  If you look at the certificate on the Details tab, look for "Serial number" and write that down, and then look for "CRL Distribution Points" and pull up one of the URLs there in your browser and open it.  In the CRL look on the "Revocation List" tab and scroll down (most recently revoked are at the top) and look for your serial number.  The CRL is the definitive answer as to whether it is actually revoked or not.

Note: occasionally this can happen out of the blue if there was a problem during upgrading/migrating a CA on their end, or if they became knowledgable of a compromise of the CA or the CA's private key, causing them to revoke the CA itself and thus revoking all certs ever issued to it.  Hopefully that's not the case, but could explain if there were to be a large number of revocations all at the same approximate moment.

We are getting a new certificate and seeing if this will take care of the problem. Thanks for your help.
