Just went through a perfect storm of change on my computer.  i built an all new rig except for the hard drives and in the meantime, moved to a new address.  So here I sit with all new hardware and a new provider and IP.  Of course FSX is asking  to activate again.  I was just wondering what to expect after that as I have a massive amount of addons loaded as well.  Am I going to need to reactivate all the scenery and aircraft I have installed?  Just a little nervous about what to expect.  Lots of topics on reinstalls but could not find anything specific to this. 

Depending on what all you have, I'd say it's pretty likely you'll be spending a lot of time reactivating everything.
