Vista windows movie maker publishing error!!!? - there was an error verifying the publishing license for this page

I can not publish my movie file!
Every time I try, an error message that states: --
* Windows Movie Maker can not save the movie to the specified location. Verify that the source files used in his films are always available, the place of publication are available, there are not enough free space on your plate and try again .*
Each is a "yes" and yet I have not been able to publish, I do not know what is the problem!
