PLEASE HELP! WINDOWS LIVE MOVIE MAKER!?

After i have my video edited and i save it in the file it needs for youtube, i click on youtube, sign into live messenger and then it says the video wasn't done publishing so it couldn't upload or something? And i figured maybe youtube just wasn't working on there but it won't upload when i try to do it straight from website either. Any help? The exact message that pops up when i try to upload from windows live is " my movie.wmv was not published succesfully" "the following problem occurred in your movie: (0x800488FA) Please help idk what to do i need this to work idk any other way to edit my videos and upload them!
