Mac OS won't let me launch the app to update. I need to get an updater.

I have now installed v. 7.7.0.
When starting it allways says new version available, but when I click "update" it´s only downloading always same version ( 7.7.0 )

A recent article. "Best Free Music Organizer Software Review & Download" was something I was looking for . I've tried a number of music catalogers over the years.... most were cumbersome or the UI was hard for me to use, because of my visual impairment. ie. 1, 2, 3 been there, done that both free and paid versions and wasn't happy . MUSICZEN looked promising so I downloaded the free version and was rather impressed in it's ease of use. It took a while for it to sort through over a TB of mp3s but that was expected . I wanted to try out some of the features of the paid version , and that's where the trouble began . I paid for a license, but never got it. My requests for it have gone unanswered and so was my request for a refund . No big deal, but thought you'd like to know that only the free version is available .

I bought this software installed it on my main pc.  Then I installed it on my downstairs pc.  I only own 2 machines with blu ray players.  My main PC had to be rebuilt with a new motherboard, so I activated it back on that same one again.  But windows was messed up in updates, and I reformatted today and it won't activate to the same pc.  Is there some way to deactivate them if you have to reformat windows or rebuild your PC.  Because I am only using 2 activations.
