Doesn't Work ???? – Free Video - Media Player and Playlist Manager for Youtube Review

When I got and saw how this app looked like, I was happy! But, when I tried to play the video it doesn't even play, even when I still have my wifi on. This app somewhat and somehow disappoints me. ? But for the design though, I would give credit to the design and effort of this app. Pleas fix this.
