Anitvirus Activation Problem

ok so I have anitivurs and have done for a while.. renewed back in April 2012. Today i upgraded from windows vista to windows 7, ive managed to install anitivirus no problem but now i can't activate it with my current key. 

 

i checked a few forums out and some just say to remove previous machines from the list under the certain software, which i have done but still, no luck...

 

any help? 

 

thanks in advance
