Question about Outlook Express

Well, I was working in a movie maker project, in fact I was able to create the final mp4 file in my computer. However, not sure why, but the file cannot be opened now. Movie maker says that the file is corrupted.

I've seen a possible solution in one of the microsoft pages. It says that I've to upload the file to onedrive and sent it to you. Well, that is exactly what I did. Hope you can fix the project file so I can continue working on it. Use the following URL to access to the file:

Hello!

I have made a movie/project on movie maker. Basically there are three parts. the 2nd and 3rd parts of my project are done. I need to add the first part of my project at the beginning of the 2nd one, but every time I try to add more clips/audio at the beginning it messes up the rest of the audio and pictures for everything else after it. How do I add audio/video to the beginning of the project? Without messing up the rest.

Thanks for helping!
