Just get the latest keys: this file (usually a zip) will contain a \keys and \scce folder. FTP all the files in each folder up to var/keys and var/scce respectively. I can't remember if newcamd uses keys or scce.
You dont have to transfer files 1 by 1. Transfer the complete folder across. And say yes to all. So transfer keys to keys folder and say yes to transfer all. And the same with scce. You dont have to open the folders up and transfer each file across. Hope this helps you for next time.
