Solved Error Code -24 when trying to transfer Sony MSP 13 projects to Vegas MSP 16

Hi. I already posted on the Vegas forum page, but I'm desperate for answers ASAP so I'm posting here too. had been using Sony Movie Studio Platinum 13 on Windows 7. I have some projects I need to work with. Problem was, when I upgraded to Windows 10 in January, Sony Movie Studio Platinum 13 stopped working. So I recently upgraded to Vegas Movie Studio Platinum 16. I'm trying to transfer some of my projects from the old SMSP 13 into the new VMSP 16. But I'm getting the message "The serial number has already been registered to another email address. Please contact MAGIX support. Error code: -24" I've been researching it for hours, and long story short, nothing's worked. I can't even send a simple email to MAGIX for support. PLEASE help! There's something really time sensitive I need to transfer. (I'm using Windows 10 Pro, 64-Bit. Intel(R) Core(TM) i7-4810MQ CPU @ 2.80GHz. 8097 MB RAM)

Hi emciv - Welcome to the MSZ Forum

1. Sony Movie Studio Platinum 13 does work OK on Windows 10.

The problem that usually causes Sony Movie Studio Platinum 13 to not work on Windows 10, is if you upgraded from Windows 7 to Windows 10 on the same computer, using the Windows upgrade function. I had the same problem when I first upgraded from Windows 7 to Windows 10. When you only do an upgrade, there is too much crap from Windows 7 that is left behind, that can cause a lot of programs to stop working.

The way to fix this problem is to do a Clean Install of Windows 10.
A clean install wipes everything from your C-Drive and only installs a fresh copy of Windows 10.
After you re-install Windows 10, you will have re-install ALL your programs.
It is a big job to do this, however you will end up with a more stable Windows 10 and lots of old programs will start working OK again.
I have a tutorial on how to re-install Windows 10 here:

2. I will assume that when you say "I'm trying to transfer some of my projects from the old SMSP 13 into the new VMSP 16", that what you really mean is you are trying to Open your old v13 projects with v16. Is this correct ?
