@etalith this tool is not new, it was developed a while ago by a fellow site member but after the recent overhaul that changed the entire site, this tool has also stopped working. Now you need to use the upload page, there's no other way yet. A new app is in development but there's no estimate for release.

@etalith All series (including series 3 as well) are on YouTube. Not sure about subtitles but those should be easily locatable if ever created.
