I must say I'm finding all this scaremongering as regards activation, whether it's for XP, FSX (or, for that matter Vista since I doubt it'll be any different) to be over the top. Of all the reinstalls of XP I've had to do (around 12 or so) or FSX (up to five now), I've only ever had to call to reactivate over the phone once. Yes, once. They didn't bat an eyelid, either. Oh, and I've swapped out hardware way more than that.As for FSX, I've reinstalled it five times now and it's activated painlessly over the internet each time.
