Updating Ghost

There's a sticky at the top of this page from 2010 saying that SP1 of Ghost has been released.

 

However, when I go to Help > About, I am offered no option to run Live Update.  The only button I have is OK.

 

My version is showing as 15.0.0.35659 and my license is showing as Activated.

 

How do I get the update?

 

Thanks
