Ghost 10 Live Update advises that I am running a prerelease or beta version

Working with Ghost 10 on an XP Pro SP3 

 

I have been using this licensed product for a few years now.  When I try to run live update, it finds an update... downloads it, but then fails to install it.  The error message is "This machine is running a prerelease or beta version of Ghost that is not supported".

 

That is news to me as it is licensed... and has successfully live updated before.

 

Any ideas as to what is causing this message would be greatly appreciated.
