Created a movie in movie maker, then when added to a bigger project it reformatted the smaller movie – now can’t use.

I created a small movie and saved it as both a project and a finished movie.  Then, not 10 minutes later, I went to add the small movie into a larger movie I was doing.  Movie maker insists on reformatting the smaller movie, but when it does, it moves the captions so they no longer match the correct pictures.  It shouldn't need to reformat when I created it in movie maker to start.  I can't correct it in the larger movie, but I can't use it either because everything is off.  How can I correct this problem?  I have spent way too long putting things together to not be able to use it!
