I had NIS installed on my laptop and desktop. My desktop hard drive died so I used my third activation to get NIS back on my computer. Now I have a new netbook that I need that 3rd activation that was wasted. My subscription just auto renewed and I don't want to cancel my subscription/refund in order to get a new key for the netbook. But on the other hand what if another one of my hard drives die in the near future? I'll have to buy a new key anyway right?
