The website where the information was stored about GunTracker is no longer working. I've accessed it, but it redirects to an entirely new one that has no connection to GunTracker. Since there isn't enough information, I recommend checking the built-in help or documentation. If it's possible, start the software and access the Help section or look in the installation directory for additional information. Developers usually place PDF or CHM files that contain everything you need to know about software's functionality.
