Those numbers are kind of small What you're actually seeing is "Luminar 4" then a space, and the the version "4.2.0 (5577)" - hard to read, but luminar 4.3 is a newer version. To more easily see your installed version choose "Help > About Lumniar 4" and you will see you are on version 4.2, NOT 4.4.2. I'm not sure that 4.3 has been rolled out to the US servers yet.
One of the things I enjoy about this forum is the constant push-back...even a "good thing" can be quickly down-graded to a "not-so-good" thing. I'm sure I am not alone in chuckling at the curmudgeon-like entertainment...
