Last year, my (licensed) version of Movie Studio 16 Platinum stopped opening on my Windows 10 computer, so I uninstalled it. Now I need to edit a video, so I reinstalled it. I have the same problem. When I start the program, it hangs on "creating windows". It seems that I updated to 17, but I can't find that information yet. I'll need to confirm. In any case, 18 appears to be subscription only, which I can't justify for the very few times I edit video. I'd like to get the software I purchased to work. Can anyone provide some guidance?
