NIS renewed for 3 years and only 1 activation?

I'm trying to install NIS '11 on my wife's laptop. She started with NIS '08 and just payed her auto renew last week. I log in to see she only has 1 activation. It seems a bit odd to me that she would have to buy a key or a 1 user/ 3 pc version. Am I missing something? The $60 auto renew should be for 3 PC's, not one.
