okay just outta curiosity so because some one buys p6 with a upgrade from p5 it then makes their p 5 license invalaid ? so im not allowed to use my p5 anymore this make no sense and because i use p5 to upgrade to 6 does that mean i cant upgrade to p 7 with that same license/? imlost now she transfered a p5 to me in a legit sale so why does that make her p 4 invalid??????
