I had chosen a video on Hulu Plus. The first commercial was reeling by. It featured a Q&A about things that have no relevance to me. When the "block" tab popped up, I presumed that it related to the ad content. I chose "yes", thinking to be spared that commercial content again. Instead, all Hulu videos are blocked. Whatever I choose, I get a window without a video screen. All other content -- questions, rating options, comments, descriptors and so on -- are present; the video screen is not. Obviously, what I chose to block was all video content from Hulu. This renders the paid subscription useless. I'm sure there's some simple way to remove a block. It would likely be useful to know that trick, not only now, but for future mishaps. What did I do? What's the correct term for it? How do I undo it it? Thank you for your time, patience and professionalism.
