A month or two ago, I downloaded the trial version of movie studio 13 (64.bit) to try it out. The trial ended, and I went to the Vegas Creative Software website today and bought the digital copy. I entered my serial key into the popup that says your trial has expired and it replied with "This application will restart to complete the upgrade process", where I click OK, it closes, then opens up with the same "your trial has expired" popup from before. I tried again after I uninstalled the trial version and installed the download version, however it gave the same outcome. I am running Windows 10 x64.
