Token invalid error - any help?

Hey, I try to use this code in my project:

https://github.com/funkenstrahlen/podcast-to-youtube/blob/master/main.rb#L12-L41

However I get an invalid token when trying to upload a video. This is what happens:

connecting to youtube account
open this url in a browser:
https://accounts.google.com/o/oauth2/auth?client_id=911313852664-tir6o945mdn2bouorhpalkecrg23dng9.apps.googleusercontent.com&redirect_uri=urn:ietf:wg:oauth:2.0:oob&scope=https://gdata.youtube.com&response_type=code&approval_prompt=force&access_type=offline
enter the access token:
