    If it is red then specify correct settings (like proxy). Also, you can check your firewall settings.

  • "Protocol "" is unknown" error

    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 program's window.

  • Error: all streams protected in this video

    Open Preferences, it located under small gear icon on the bottom left side of app's window. Next open Audio output tab and select desired iTunes options.

  • It says X amount of mb skipped. Why?

    This is a normal situation when Boost mode is enabled. It means that the app downloads only audio track skipping the video part. Output audio quality is the same but is saves a lot of traffic and time.

  • Error: Connection closed

    Your playlist is private, so make it public before download or setup YouTube Authorization in the program's Preferences

  • no access to iTunes:

    This is one of those hard to replicate bug, but the majority of our users who are affected by this issue reported that iTunes reinstall fixes this bug.

  • 100% usage

    Also, we recommend you to remove completed downloads. Large list can cause this problem. To do it select "minus" icon at the left bottom corner of program's window. And select "Remove completed".
