While some of the features look cool, I do fairly simple edits in Movie Studio and the new version is not working for me.
I upgraded to install on a new computer (I started with 9 and have upgraded several times.) Now, I am very frustrated and would like to trade my 18 key in for a permanent v16 key. Any way to do that?
Movie Studio 18 is not a VEGAS product and support for it is not available on this site. However, support for Movie Studio 18 is available from the MAGIX user forum https://www.magix.info/us/video-forum/movie-edit-pro/
Re downgrading, no idea. You might ask emailing infoservice@magix.net
