Hello! I have a problem with my Windows Movie Maker. Namely, I have been imported some wmv files and I have joined them, because I was planning to make some small movie, but when I tried to save this movie, I got message which said that I should change location for saving and if I am sure were those files still available.
Hello! I think that reinstall your Windows Movie Maker will solve your problem. Also, you could try to reformat your files, too. That could be helpful. I had same problem as you do now, and reinstalling Windows Movie Maker helped me. I hope that it will be helpful for you, too.
