Thanks for responding so quickly! One more question: It is o.k. to install on both of my flightsim computers (I have a computer in two different rooms in my house), is that correct?
Yes. You have 6 activations available so, there are no problems installing on several computers at the same time.
And, if you finish your activations, and you obtained the last one less than 90 days before, you can always email us for a reactivation. Otherwise, it's all automatic.
