I am mid-project. I processed a bunch of videos last night, no problem. This morning, none of my project files would open. My computer could not open Movie Studio 14.0 Platinum. I tried "Admin", I tried re-boot, nothing worked. So I re-installed (hoping it would save my presets), but now the re-install asks for my serial number. When I provide it, it doesn't accept it, like it's dead. I run Windows 11 on an older PC. I have plenty of RAM, and a fast processor.
