while i think that curious labs has a right to protect themselves this whole activation idea wont really work, an example of a workaround, while a small pain, will, if i understand the way the activation code is to be applied, work. before installing the new version of pro pack or poser or what ever, make a full FILE backup of the c drive, since the instillation is ok for 7 days before the activation code is needed it would be possible to restore the system drive from backup and have a system that never had the pro pack installed, and then start the process again. simple and fairly easy and those that you are trying to stop with the activation code will be able to do this and get your product for nothing. Priacy is a two way thing, as by some of the comments on these threads those that would always buy your products would not be happy at all with the plan and may end up getting a cracked version out of spite, priates steal software because its too expensive, company put the price of there software up because they are losing money, viscous cycle or what.
