Maybe I need to clarify,  If I go to Menu/Help/Update Online with MEP, it shows that an update is available.  So I follow instructionsand get a download, but when I try to install, a message says that I must have "MAGIX Video Deluxe 2015 Plus" installed before the update can be peformed. So the question is why do I need Video Deluxe 2105 Plus to update Movie Edit Pro? 

I also tried to update directly from the Magix website, but get the same result.
