I just finish a halo movie, i want to publish it and upload it to youtube, but when i publish it.

A error message comes up and movie maker closes on me. It took me like 4 or 5 hours to make this stupid thing, and im no going down without a fight

So help me?

Piece of advice when using WMM...

Save often!

Get your project started... save it.
Make a few changes... save it.
When you're done... save it.
Then, as a last step, save it again, but this time as a movie file.
