What was the problem...?
The first problem I had was I must have been pressing the Wii remote buttons in the incorrect sequence although i was sure I was doing it in the right order !!! LOL
When I managed to get Preloader .27 to boot I ran the update for preloader .28 . When I switched the Wii off it booted up into preloader .27 again. I then waited the 30 secs for the update and installed it and now as is good.
