Welcome to the forums. You need to make better subject lines, as "Help !!!!" isn't going to grab many people's attention.
You also need a bittorrent client. The torrent file is just metadata, telling the client where to find the data and describing what it'll look like. You might notice that the torrent itself is very small (less than half a meg). A video file is typically fairly large (like in the neighborhood of 175 megs). This would be a good tipoff that you didn't download the video file itself yet.

Several popular bittorrent clients include Azureus and BitTornado. Google work is left as an exercise to the reader.
