Hi wjung,

Well, I probably can't give you a complete list, as we don't necessarily want to divulge too much information on our copy-protection system. But the main ones are the hard disk and operating system. If you change your hard disk (including repartitioning, or changing disk space on a VM, etc...), or upgrade your version of Windows (including Windows Updates), you risk having a magic number change, and need to reactivate the software. However, in any case, you should always be ready to expect a magic number change whenever you make a major hardware change on any machines that uses PlanetPress.

Do you have a specific scenario in mind? Maybe you can tell us what you want to accomplish, and we can tell you whether or not you risk having a magic number change.
