YouTube has changed their code and the earlier versions of BYTubeD have stopped working. I have made the appropriate changes and BYTubeD 1.0.6Beta is working. Please install 1.0.6Beta from here or 1.0.6 from here. For more details of 1.0.6Beta please see this post. If you observe any issues please post them on this page. I will try and fix them.
