On the weekend I went to watch some catch up TV on one of my computers. However the website told me I needed Flash Player. I was puzzled by this as I have watched catch up TV on that machine previously. I checked Control Panel and sure enough there was no Flash Player installed. I downloaded a new edition of Flash Player, compatible with my browser, installed it and restarted the machine. Again I was unable to watch the program. I went to my other computer and watched the program, but the first machine continues to not detect Flash Player and I am puzzled by this. That I was able to watch the program on one computer suggests that it is not a problem with the website, but what is going on?
