Ok another question which I need an answer if possible,
How is it that my Weight has fallen from 30k to under 1K, and last night by going to bed and leaving the programme open I receive more payment for mining and it came from an receive address that I have got for one of my friends?
Thanks Guys,

Hi, not really sure about the network weight thing, but it could be to do with someone else with a larger wallet turning on theirs to stake where they did not have it on before?
Just a thought.
