Hello Mike,
I understand, the LiveUpdate Administrator 2.3 is a new Tool.
If this is a major situation, I would suggest open a web case
You can log a case on web portal:
QuickStart Guide - Create and Manage Support Cases in SymWISE
http://www.symantec.com/docs/HOWTO31132
How to update a support case and upload diagnostic files with MySupport
http://www.symantec.com/docs/TECH71023
Once, a case is created, provide us the case # and we will do the needful.
