Quote - You have to blame the dishonesty of those who pirate for your plight. As a Zbrush user I feel your pain.

The irony is that this measures don't stop piracy. Pirated copies can be installed on any machine any number of times. If people pirating the software get less hassle and more value then honest paying customers, it is a problem. The key to combat piracy isn't enganing in meaningless arms race which is a losing battle for any kind of software but AAA games, but to add value to the paying customers.
