Is there any hope if you accidentitaly uninstall ZCM on the primary server that was hosting the CA root certificate????

I have 3 primary servers in the zone. I have reinstalled ZCM on the server that had the CA, and now obviously the clients do not like that newly installed server.

I am getting This in the ZCC: Error in the TLS certificate chain. Message: A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider..

Can I restore the cert somehow? I have a backup of the server before I messed things up, is it possible to copy files from the backup or restore this somehow?
