I have a windows account and everything you need to use movie maker. Everything was working fine until now where I try uploading videos to youtube and it says that I have an invalid password. I already know I'm typing the password correctly. The username for my channel is automatically remembered in Movie Maker. This problem has never occurred before and I've had to reset my password, but I still get no results and the same invalid password error shows up when I try signing in and uploading to youtube through Movie Maker. Is this a glitch with the Windows update that happened today (for me at least) or is it something troubling? I also know that youtube doesn't let you sign in with just your username anymore, just your e-mail (if you sign into youtube using their homepage at least). So has Movie Maker been changed and why is this error occurring when I know I'm typing my password in correctly? Is it just an error that came with the latest Windows update, a problem with Movie Maker itself or just a change in how to log in and upload with Movie Maker? Please help.
