Unable to update IBM Rational Product Updater 6.0.1

Installed 6.0 at home a couple of months ago from the DVD.  Decided tonight
to check/get the latest updates.
 
I click Help/Software Updates/IBM Rational Product Updater.

It shows me I'm at IBM Rational Web Developer 6.0.0.1, Interim Fix 6.0.0.1
and IBM WDSC for iSseries 6.0.0, Interim fixes 6.0.0.1 installed.

I click Find Updates and it tell me "There are required updates for the
Product Updater: IBM Rational Product Updater 6.0.1. It is necessary to
install these updates and restart before continuing."

I click OK and it says "Applying Updates".
In less than 15 seconds it stops and I see these messages at the top of the
screen:
Unable to complete action for feature "IBM Rational Product Updater 6.0.1"
due to errors.

Is maybe the site down?  (Though I retried several time over a 45 minute
period.)  

I'm running over a cable modem (Comcast) and I stopped my firewall (Zone
Alarm).  Don't believe I have any proxy issues.

Anyone else run into this?  Have a solution?

Thanks, Sam
