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!
