Subscription renewal question ref. PC count

Two part question.

 

My 3 PC subscription, which expires in 15 days, just auto renewed and charged me $59.39 through email. I have not yet pressed the "Subscribe Now" button on any of my 3 pcs, should I go ahead and hit the subscribe now on each pc or will it do it automatically at the expiration?

 

My main question is when I log into my account it is showing the new expiration date but shows protection for only for "1" PC, and "none" remaining under activations. Will all 3 pcs still be covered even though it is showing only 1 under my account?
