I decided to start again not borrowing anything from what I had previously. This time it worked flawlessly. I must conclude that I had made a mistake somewhere in my previous setup. I'm not inclined to spend the time and compare what I had previously to what I have now as the likliest outcome would be the spotting of a mistake on my part. So I am going to simply assume that I made a mistake in my previous project, archive it and move on.
Don't throw the towel !
Of course, you wish your project to get going ...
