(404) Not Found

[noammaoz]

I'm trying to download the https://www.youtube.com/watch?v=q0hyYWKXF0Q and i'm getting exception of "The remote server returned an error: (404) Not Found."

This is happening in Decipherer -> DecipherWithVersion
string jsUrl = string.Format("http://s.ytimg.com/yts/jsbin/player{0}.js", cipherVersion);
// jsURL is http://s.ytimg.com/yts/jsbin/player/45e4d51d/player_ias.vflset/en_US/base.js
string js = HttpHelper.DownloadString(jsUrl);

Any idea?
