Norton subscription info not updated

Hi,

 

I recently renewed my subscription online rather than buying the new software; I realised it was more expensive but wanted the added convenience. Anyway, my subscription info has been updated on the computer I used to complete the transaction, but my other computers, active under that serial key (3 computer usage), still says it needs to be renewed. Is there something additional that I need to do?

 

Regards,
