Can't update Norton Toolbar beyond 2012.5.7.2

One of my machines has successfully updated NIS to the latest version, 19.9.0.9, but my Norton Toolbar is stuck at 2012.5.7.2.  I am running Firefox 15.0.1   I know that 2012.7.5.2 which adds support for Firefox 15 has been out since 8/27. 

 

I have run LiveUpdate about a million times and it won't get it.  I have also run AutoFix and it didn't resolve it either.   I am running Windows XP Pro SP3.

 

Any ideas how to update the Toolbar?

 

As a bizarre side note, the toolbar is actually working.  My other PC has a newer version of the Toolbar (2012.7.4.1) but it has been disabled by Firefox 15.0.1, saying that it is incompatible.  Strange.
