Hi, I'm Matt. I am novice user of Movie Studio 14.0 and I am getting the following message when I try to open a mp4 in Movie Studio 14.0. I am not sure why this is happening, especially when I have been able to do this in the past. Other mp4s I've created with my Logitech webcam can be opened just fine, but not the one I recorded last Friday. Any suggestions?
