Ultimate Video Player giving an undefined error

Just purchased the Ultimate Video Player and I am having a terrible time trying to get my videos to play.

I am trying to use a youtube playlist and there are 3 videos in this playlist and I got the URL, which is: https://www.youtube.com/playlist?list=PLi63p0XaMMGHfa_63CbooF0uAFYnl37ed

I put that into the Playlist Source of the Playlist I have added and it is now giving me this error:

Error loading youtube undefined! PLi63p0XaMMGHfa_63CbooF0uAFYnl37ed

At the end of that undefined is the ending of the URL of the playlist.

It is not working. I need someone to help me figure this out. I have also looked at the video tutorial, so please can someone help me?
