Problem with RH8 up2date

[grenoml <grenoml yahoo com>]

I installed RH8 recently on a new machine and just ran up2date for the
first time and selected everything for update (including kernel items).
 It prompted me for the root password and then took a while but all the
packages were downloaded and then repackaged and then it said
'installing /var/spool/up2date/kernel2.4.18-19.8.0.athlon.rpm' and the
little watch came up and that's all she wrote... the install window
went completely dead (no window refreshes - nothin').  So I looked in
/var/log/messages and found this:
----------------------
Dec 29 19:22:35 tltdev01-lin01 userhelper: pam_timestamp: timestamp
file `/var/run/sudo/greno/unknown:root' is too old, disallowing access
to up2date for UID 500
Dec 29 19:31:14 tltdev01-lin01 userhelper: pam_timestamp: timestamp
file `/var/run/sudo/greno/unknown:root' is too old, disallowing access
to up2date for UID 500
Dec 29 21:20:57 tltdev01-lin01 sshd(pam_unix)[30904]: session opened
for user greno by (uid=500)
----------------------

So I need a little help here.  

What state is my system in.  I have not rebooted because I'm afraid it
might not come back up since it was dealing with a kernel update.  

What should I do to correct the 'too old' problem in the message log.

Can I just kill the install window and rerun up2date again?

Thanks,
Gerry Reno
