BTW I now have the button back and it shows me the 61 files available but tells me Iu should update up2date first.
I managed to get the new cert down and ran up2date up2date and got this..
[root@LinuxBox root]# wget -q -O - https://rhn.redhat.com/help/new-cert.sh
The file /usr/share/rhn/RHNS-CA-CERT has already been updated.
No further action is necessary.
[root@LinuxBox root]# up2date up2date
