I am having trouble with Windows Movie Maker - I usually use it to edit all of my videos, but it is causing me quite a bit of hassle this time. I edited an hour of a four hour long video last night, with the pictures and audio being completely separate files. I go to open it up today, and the audio won't load with the video. I can remove the audio and add in literally any other audio clips into the thing and it works, I can remove the clips and add in any other clips and it will work, but for some reason the already saved file I had of the edited files will not work together, unless I am to re edit the entire thing. I have tried closing and re-opening the application several times, but to no avail - I have even tried removing the audio clip and, instead of adding a different audio file to see if it would work with it, adding back the normal audio file - and still, nothing. I have never encountered this problem before, and I can't find anyone else online who has had this problem either. Please help.
