I've had this YouTube account for at least 7 years; Google+ came along and gave it a funky email address they synthesized (and I have no record of). They also decided to make it appear as a secondary account under a Gmail address I would not have selected. (always hated this)
Today when I selected this account to upload (as I did yesterday and the days before) it gave me this 403 error! No matter what I do I can't get it to go away. I can log into the YouTube account directly by using the firstname.lastname@example.org and see all of my 180+ clips.
So then I try uploading using the first account listed above; it publishes my new clip under THAT gmail account which has always had zero video clips because that's not used for YouTube! Has anybody else been caught up in such frustrating nonsense?
Guess I will render and upload manually unless somebody has an idea what happened to me and what to do. Thanks
