Okay, so I have a computer that I have recently put Movie Maker onto. I have tried putting videos on and they are corrupted with Error:0x87160139. The files are compatible with WMM and I have tried everything I can think of including looking up on YT - one person put on desktop, which hasn't worked. I have followed your advice on what to do from other people who have asked but I can not find anything that'll work. Any help appreciated.
