I’ve noticed this happening to music videos, but not many others. It even happens if i go to the same music video that I previously downloaded with no problems. I tried downloading the same music video from a different website and it worked. Went back to YouTube, same problem. It seems to be happening to music videos only or at least that is what I’ve seen so far. I hope this will help out.
I’m having the same problem too, and I’ve noticed that a lot of YouTube music videos are now displaying lyrics, where they weren’t a few days ago. I wonder if there was some kinda upgrade on YouTube that’s not compatible with Apowersoft?
