I'm trying to log into my Facetime but I get the following error "The server encountered an error processing registration. Please try again later." Now I've found this advice in on another site: " (make sure Facetime is closed) 1. In Spotlight type in "Keychain Access" 2. There will be a certificate issued by Apple iPhone Device CA - This certificate was signed by an unknown authority. Delete this certificate (or move it to the desktop, out of the keychain access store) 3. Launch Facetime and login - this time there will be no error..." This seemed to work for everyone else but myself, when I go into keychain access there's no certificate called 'Apple iPhone Device CA'. Anyone else run into this problem? Any help would be appreciated.
