Box Office channal? Boxing

All week i have seen the bxing advertised on sky box office, and also all week it has kept disappearing off the same channel. At the momment it is missing again, and the channel keeps trying to update. I have the new firmware and all of my other channels can update properly. I had this problem the other week when ricky hatton was fighting, and basically it just cameback on the channel. Will this happen again this week does anybdy know. thank u
