drhouse / YouTube Unblocker

Shame it doesn't work. Been looking for a way to download blocked videos for so long now. I got all excited when I saw this script. I did click on it in the TamperMonkey menu, and it said it was unblocking the video, but it still didn't work. :-( This is the video I especially want to download. https://www.youtube.com/watch?v=gZ9kCdGo25I Please let me know if you can get it to work for this video?

THANKS YOU!
