Movie Maker stops working

I have made a movie project in Windows Movie Maker which includes images, videos n audio. When I select the save movie option it gives me certain more options as to in which format I want to save my movie. When I select any of them Movie Maker stops working. It shows a popup that "Movie Maker has stopped working. We need to close the program and will find a solution if available". The overall size of the movie goes upto 200-300MB when I keep the mouse pointer on any of the options. For eg. the movie is of 13.30 minutes and if I select "Save Movie for Computer option" it shows me the size will go upto 40.71MB per minute of movie. I tried selecting the least size options too like "Save Movie for email" in which the size goes upto 11.42MB per minute of movie. Still Movie Maker stops working. The operation just doesn`t get started.
