I made a Kingdom Hearts AMV on Movie Maker (With clips from this site) and whenever I go onto Finish Movie>Save to my computer, the program closes while it's saving. It never saves the file properly. It only saves one second of it. I can't use Video Converter websites because it's still a MSWMM file, and they don't accept that file. (I've tried loads of different sites) I've tried to save it several times now, and it still won't work.
