I can only ask, when has it been the authors responsibility to replace peoples keyfiles and registration numbers because the customers doesn't store them in safe places???
With attitudes like that, it is no wonder people would rather download a pirate version than support developers who think "customer service" is non existance. Developers should be jumping through hoops for customers, not placing silly obsticles in the way.
