What are the 'Activation' requirements?

Have just been browsing the NGX forum, Checking on as much of the usual new product hickups and solutions while waiting for the PMDG servers to recover from what must have been a huge demand, before making my purchase.I came accross a thread that caught my eye. Not regarding the subject, but the remark made by Ryan in his answer to a customer: Your key is reset - try installation again. If it fails submit a support ticket please, do not keep trying it over and over as this will just run you out of activations again. Does this meen that there is a limit on the number of times you can activate this product? And does this also apply to my 747 & md-11? What happens if after i have upgraded my PC or O/S or just had serious software problems involving multiple reinstalls? Can i end up with product i can no longer activate?

I'm sure if you run out of activations in the future a quick support ticket will solve the problem.
