help :( Rated 4 out of 5 stars

I've been using it since years ago and I love it. I wish it didn't let me rate the videos or write comments, actually since a while back it doesn't let me comment, but that's OK.
My main concern is that the videos don't play at all. I can see the icon moving, and I could even download videos I couldn't watch on youtube. Please fix it!!! I'll try to download an older version but I'm not sure if they're available or how to downgrade it :(
