I have contacted Microsoft support weeks ago to see if they can fix this for me and have had no response. When i try to save my file as a movie, the whole file corrupts and i cannot save it. I have uploaded the file to OneDrive and made it public, here is the link https://onedrive.live.com/redir?resid=51BA4AD0E7410F79!1150&authkey=!AMk2pdiMSkC-I3E&ithint=file%2c.wlmp . I really need to know if it is fixable so I know if i have to make the whole thing again, which i hope not because it took me ages. Thanks :)
