Check connection to YouTube.com in the application Preferences. Open Preferences and switch to the Network tab. There is a small indicator which displays connection status to YouTube server. It is located at the bottom left corner. If it's red then something is blocking an internet coonection. Check your firewall and antivirus or specify correct proxy settings.
The content in the clipboard you are trying to paste is incorrect. Maybe you've copied some extra characters and the video link became broken. Try to drag'n'drop the link on the app window instead.
This means that all streams in that video are DRM-protected and unable to be downloaded. You can read more about RTMP protocol and protected streams at Wikipedia.
