I am having a very difficult time adding saved projects from Movie Maker to other saved projects. When I go to the File tab, I can open the first part of the movie. However, when I add or try to add the other saved projects, the first saved project goes away and I only get the next saved project. Here is an example.


Beginning Credits are opened when I go to File, then click on Open Project. The credits show up.
 
I go back to File, Open Existing Project, the beginning credits go away and the next existing project comes on.
 
I work with Windows 8.
Thank you.
