I have noticed that many people are having the same issue I have with the movie maker not saving.

I went to save my movie after I finished putting it all together with pictures and sound. I go through all the steps you have to to save it and all it dose it sit there for like 10 min with this window:

Then after it has sat there for a while I get this window:

I am getting very frustrated with it not saving. I went to save a different video I made and it saved. I did everything the same as the other video. The only difference is the one that saved is 15 min, and the one that wont save is 45 min.

What can I do to fix this problem. I need a salutation fast. I am on a deadline.

Thank you and have a nice day.
