I've extracted audio countlessly, but this one channel, I cannot extract. I am left with the final line of downloading jsplayer. There is no network activity going on while running the .exe, so it seems to be stuck.
Few examples of the videos of what is working and what is not.
Working: 1
Working: 2
Not working: 1
Not working: 2

As you can see, videos on "Epic Music VN"channel does not work and the videos on "Epic Music VN X" works.

This is another video which also downloads a player during extraction and it works just to eliminate a possibility that something is wrong on my end.
