Hi I have Windows Movie Maker 2012 and all my video drivers are up to date.

I saved all my media files onto my OneDrive, rather than onto my actual computer. They all play fine as a movie maker Project, but twice now I have been prevented from saving it as a Final Movie, because of an Error 0x87160139.

When I double click the media files with a yellow triangle it says that they are corrupt or unavailable, which doesn't make sense because they work great as a project. All the media files are either mp4's, jpg's, or png's.

It needs to save as a final movie in two days. Thanks in advance.  

I read on an old forum from 2010 that maybe Windows Movie Maker doesn't accept movies that have been split or trimmed, because then they have two media files under the same name. I have been splitting and trimming movies all throughout the project (thats why I used Movie Maker), so hopefully this isn't the case.

My main suspicion is that Movie Maker can't find the media files because they are all on my OneDrive. 

Please help!
