Oh dear- just been fighting with Norton anti virus- why do they always make it so hard. Looking for the product number for ages! Nowhere to be seen. Finally....finally ( after much cursing and abusing of this product) I find it hidden away as part of the wrapping- grrrrr Now its 11.45pm, I'm beyond tired and I have to get up early grrrrrrr I think I'm too tired to go to bed.
