Hi Kaz,
Well done for even starting the set-up process. I'm convinced that, like animals, computers have minds of their own. However, unlike animals, they are impossible to understand. I only get along with mine (computer that is) when it's behaving nicely. At other times I hand over to hubby. This works out well because he only deals with our animals when they are behaving nicely and at other times he hands over to me. Team work, eh ?!
Good luck.
