Original Title: Help needed with windows movie maker

For the last few years I have been using movie maker 2.6 and love it. Since the upgrade to windows 8.1 it is no longer compatible and have to use the new movie maker. I am going absolutely crazy!!!! I can save the project but cannot save it as a movie! It gets to a certain point and says not enough memory! I have plenty of memory and hard drive available. I have tried saving it in all the available options with no success. 

What should be a fun project is now a nightmare. For the last 72 hours I have tried everything, reducing resolution on photos, saving in the different options, etc, but no use!!!

Please help!!! Urgent!! It was a project for Monday 15th of June. I have spent weeks organising the photos, choosing the music, trying to save it etc. What can I do?
