I have spent hours editing a video in Movie Maker. I have Windows 8.1 and and using the 2012 version of Movie Maker. The video was working well and saving fine too, then I go to open it and it says that it cannot open as it may be corrupt. I really don't want to restart the whole video. I have also followed the steps on here on how to fix a corrupt file but when I entered my problem to the support team, it would not send through. Please help :)
