I just purchased and installed the Vegas Movie Studio 17.0 Platinum today. In my projects I can insert pictures but I can not insert my movie files? Not even my captures I recorded on my own PC. Anytime I try to drag a video file it says "The activation code is incorrect. Please make sure it has been entered correctly or contact the MAGIX customer service: www.support.magix.net

I have tried uninstalling and reinstalling and ensured to enter the correct serial number. Looking for guidance on what I need to do. Never had this issue in the past with previous Vegas movie studios programs...
