What happened? – MyTube - Music for youtube Review

I got this app a few months ago so that I could play YouTube videos in the background without paying for it. As of recently, I can't load a single video without the place where the video is supposed to play going black and not responding. It does this with EVERY SINGLE VIDEO. What's going on? I even tried deleting it and reinstalling it to see if that would fix it and it didn't.
