Yep, sure have. Unfortunately there seems to be little you can do except 'try again later'.
Sometimes that means just doing it again and again until it works, sometimes it just won't and you need to walk away.
As you now know, it can do this for a week sometimes... just stick with it or load to youtube in the interim if you need to link it in a post.
Good luck!
I've been trying again and again for a week now, but somehow it doesn't work. It's just strange that so many new videos have been posted in the meantime. Don't the others have any problems, or try them all much more often.
