Maybe you can setup a remote session and run your home Vista system from
your work computer.... as you see there's no option to go from a Vista
project file to an MM2.1 one.
Another option is to install v2.6 on your Vista system and use it instead of
MM6. See my website's Setup Movie Maker > Vista MM2.6 page.
