When I bought the Magix Movie Edit Pro 2013 Plus back in 2013, it worked OK on my computer (HP p7-1520t). But now the program no longer reads or recognizes MOV files (obtained from my Nikon Coolpix L820 camera). I get a message: "To use MPEG-4 Basic function, a one-time activation is required." And when I click to proceed with Activation, I get another message: "The activation of MPEG4 Basic failed. If you are using the program as a guest, please repeat the activation procedure with administrator rights".
Notes:
1) The Magix Movie Edit Pro 2013 Plus works OK for MOV files obtained from a Panasonic Lumix DMC-ZS8 camera.
2) Within the last year, my computer has changed the operating system to Windows 10.
3) Within the last year, I have also installed Norton Security onto my computer.
