When I sign in to Movie Maker, it happens automatically, so I don't know which account it's signing me in with. However, when I try to upload my video to YouTube, it tells me I've failed to publish & to sign in with a different account!!! I've tried creating an alias to my Microsoft account, no go. I've created a whole new gmail account & tried that, no go. What do I have to do to satisfy whatever bizarre logic this darned algorithm is using? 'Scuse the frustration but it's taken me half a day to learn that I had to download ALL of Windows Essentials to use Movie Maker, then learn how to make my first video, then add the music, then synch the two components, only to be thwarted at the very last hurdle by some dumb sub routine! It's enough to make a weaker man cry! :)

Thanks.
