Update:

It was a very long day yesterday!
I realised this morning that I had the wrong device selected in MCS. It compiles now but there ares still problems.
I did see "Hello World" appear on the first line of the LCD but it took a couple of seconds to get there...and it only happened once.
I obviously have the set-ups all messed up. I can't even do a simple LED Blink on RC0

Back to the datasheet.
