I know a 16 year old kid who has hacked copies of almost every popular graphics program, including PPP, 3d Studio, Lightwave, PS, you name it. Obviously, the security measures taken by those companies were useless. I look at software registration and security codes like those teeny little brass locks on a childs piggy bank. Sure, it keeps it closed, but with a flick of your wrist you can tear it right off. It only keeps an honest man honest. I think it odd that CL wants so much info from me and yet it does not trust me to be that honest man. From personal experience with CL over registration numbers - Mr. Hernandez WILL have CL's lawyers on you before he even bothers to see if there is an error. I promise you if they get they're information screwed up concerning your serial number, as they did with me, you will be getting email from some boob who calls himself the "Pirate Killer". Thankfully there are cooler, more insightful heads at CL than Mr. Hernandez, and all was made well after I proved to them I was indeed a registered owner of Poser. All I can see is that if you make things more difficult for the people who desire to do the right thing, you take a great risk in losing their good faith. If you are going to be in the business of writing softeware, then, like Ironbear said, you have to accept as a consequence of the business that you are going to be pirated. It's truly sad that people feel they need to steal everything they can get their hands on, but that's the world.
