my onecare expired and i bought a new one today with the cd and cd key. do i only need to click renew and enter the cd key and everythings done? no need to confirm email or somethign? cause kinda weird i bought a box and all i took from it was the cd key and didn't even use the cd. it expired like 2 days ago soo im guessing it'll take 24hrs to change. but i just want to confirm that it's good and done.
