Fix required urgently

I originaly bought Norton Internet security 2009 for my pc at home. we had 2 other PC's which i then bought a further copy of norten internet security 2009 for however i realised that i could use the original copy to cover our PC's which i did. My subscription has just run out. No probs, no need to pay again as i have another copy wiith a product key, just uninstall and launch the new product key. Unfortunately even though i have paid for this copy as well it is completely blocked. I now find myself with no protection which may cost fortunes if a virous hits all 3 PC's. Please advise

 

Please note extremely pee'd of with no easy way to contact Norten
