Authentication code for Movie Studio 13 Kevin-Arkin wrote on 8/5/2025, 1:04 PM Something happened to my program so I deleted it and reinstalled it. When I start up, I try to use the Optional Authentication Code as instructed, and all I get is "Invalid". Got any ideas on what to do now? Kevin Arkin Back to post

It's only the later versions (17 onwards) that are dealt with here as the program shifted to a differently based program altogether. A link to the correct Vegas forum can been seen at the bottom of this page. Ray. 1
