I create a simple credits saying 'hello', and when i save the movie, it says;

Windows Movie Maker cannot save the movie to the specified location. Verify
that the original source files that were used in the movie are still
available. that the saving location is still available. and that there is
enough disk space available and then try again

I can even make "credit or titles", how do i expect do make title with
music? *sigh

Do you know any solution? I think i want to uninstall MM2 and reinstall
again. Please tell me how to do it. Thanks
