So, i was editing the movie i used 2 hours on editing, i was just about to finish it, just set something to 4x speed and somehow all my files cant be used. I did also have files that were 32x speed'ed up. It says that the files are damaged or something movie maker can't handle. I did edit 3 videos same type before. This is god damm annoying cause i have a short deadline so i need to finish it. PLEASE HELP ME. Im stuck! I can't delete it all again.

Anwser as soon as possible!
