I keep getting this error code every time I try to export a video as an MP3. It says 'This email address has already been registered to another account, please contact MAGIX support.' I can save it as a WMV, but it's not fullscreen, and that's an issue. I have Movie Studio 14.0, a Windows 10 laptop, and my system is up to date. I can't contact MAGIX because their support team is only available during my school hours. And suggestions? I really need to get something exported by March 2cnd, because that's a due date for a project I'm working on ^^;

Thank you!
