We have no way to deterine a machine's configuration from a Challenge Code... <<<<<<<<< The installer must use a set procedure that interprets certain machine parameters to create the challenge code, otherwise the system couldn't recognise when there is a change in those machine parameters. Knowledge of that procedure logically implies an ability to interpret the code to ascertain those machine parameters. >>>>>>>>>> ...no information is sent to CL without your deliberate action. What do you think happens when you register any piece of software? The company receives all of your registration information and your serial number. We simply add the Challenge code to unlock your software. <<<<<<<<<< I can send my registration information as a deliberate action because I know what it consists of. I don't know what information the challenge code represents, so while the action of sending it may be 'deliberate', it isn't an informed choice. All I do know about the challenge code (and that's from accepting what CL says about it) is that it is based on the configuration of my computer. You won't tell us how the code is generated; or what it represents, so presumably we are supposed to just take your word for it that information about our private existences cannot be derived from the challenge code. Despite the high regard I have for Curious Labs, I won't accept that scenario. Luckily for me (not having purchased the Pro Pack) I have a clear choice when the next version of Poser comes along. I either accept a secret code placed on my hard drive, that I cannot control; and accept 'deliberately' sending a copy of that secret code to an outside organisation - or I don't use the new version of Poser. It seems hard to believe that I won't be making further use of Poser (< shakes head and shivers at horrible, cold realisation. >), and even harder to believe that it's the program's owners causing that.
