Whenever I try to save this one video file, it keps saying that I've altered the imported files since I imported them. They have not been touched or altered in any way. When I preview the video, everything shows up, and it works fine. However, when I try to render it as WMV, it always says that the files aren't available. What can I do that doesn't involve redoing it completely? The program is really frustrating me, and I'm beginning to hate Windows. Its always giving me problems like this.
