Just a little update re my problem with Flash player or whatever the issue is with the lack of ability to view live news streaming. As you have suggested I have installed Google Chrome, and just as I had suspected I find I have the very same problem with it as I do with Internet Explorer 11.
In other words, I am still unable to view streaming video. By the way, I am still able to view YouTube video.
Looks like it is a reformat operation is the only solution. I am going to put that job off as long as I can. Unless someone else can direct me to fix that works.
