Hello, I purchased "Video Deluxe MX Plus" a few years ago. The serial number is Removed by Moderator version: 11.0.0.42. I changed computers (to a laptop running Windows 11) and reinstalled the software on January 14, 2026, but I can't activate it. I also changed my email address. How can I activate my software so I can work with AVCHD files? Thank you for your help.
