2b) Changing drive letters/removable drive bays/etc.: This should not affect your installation and should not require reauthorization. If this security system is checking for hardware codes to generate the challenge code, what hardware is it checking? The only way I can see this working as has been stated is if it checks the serial number of the harddrive it's on and some non-replaceable serial number on the motherboard. Because if it isn't restricted to this, that means we'll not know if Poser will stop working if we replace a memory module, or switch out the processor, or the floppy drive controller or videocard or... In short, what I demand to know, and what everyone who wants this program has the right to know, is what is being checked by the code generator? Please don't insult our intelligence by saying it's a security issue. We all know that the program will be cracked within two weeks. I want to know exactly what the ramifications are. If Curious Labs can't say for certain that switching out hardware won't cause the security system to trip, then they have no business inflicting the legitimate consumers with such a faulty system.
