So, I downloaded the NGX last night, and activated it. Love it. It's a Masterpiece. I'm thinking of formatting the HD this weekend, and doing a fresh install. What happens, when I install the NGX again, and try to Re-Activate? Will it go smooth, or is something else required, since I've already activated it. (about 14hours now) Appreciate the info.

+ 1 on that, I'm intending to do the same.Is there a way of, maybe, de-activate upon uninstall, so when we install it again, the activation can run smoothly?

+1 ...but I won't format my HD. I will only reinstall the FSX. Is there some problem? I believe that I not need open a ticket for this question.

Can anyone from PMDG Comment on this, when able? Thanks.

If you reinstall the plane after a reformat, I believe you'll have to reactivate. Now you shouldn't have an issue with that, but if you do, just send a support ticket to PMDG and they'll get you sorted. For the others in the topic, if all if you want to do is reinstall the plane after reinstalling FSX, you shouldn't have to reactivate. The licensing system should still know that you've activated the NGX on your system. Just like above though, if you have an issue reactivating, just send PMDG a support ticket.
