You are using an outdated version of youtube-dl (one year old), Youtube has done some breaking changes since then. Please upgrade to the last version, see our FAQ if you have problems updating.

Right. I discovred that after I subitted. I was waiting for the download using the latest version to finish to confirm and close the ticket.
Thanks.
