Add me to the list of those who oppose the new security system...both the Challenge Code AND ESPECIALLY the dongle!!! I've been using 3DS Max for a few years and even after they FINALLY abandoned the hardware dongle and went to the challenge code system it has been a nightmare. Besides, how can they require a dongle at this stage?!! I haven't even gotten my P5 yet and I've already got a headache. Look, I support Curious Labs' right to protect itself against piracy, but I also agree that this system does little or nothing to prevent that. Legitimate customers will suffer the most for this. The pirates will find a way around it, if they haven't already.
