BAM, JKeller is accurate. But here's a little more detail from our end. There is a grace period during which our protected/locked applications can run without registration. So if you do not have an internet connection for the machine you've installed the application on, you can still run that application for a limited period of time. During the grace period you will need to send us an email, snail mail or phone call to get the unlock code and enter it the next time you start up the app. Then you are unlocked and registered, and don't ever need to connect with us again, unless you want to do another install on another machine. After the grace period has expired, if you haven't registered before that time, you will need the unlock code to use the application again. The simplest registration/unlocking process will be for those who install the application on a internet connected machine. The access to our server to unlock the app will occur instantly. And the unlocking code only gets generated that first time you register, hence you only need to connect to us once to unlock the app. The unlock code is then securely stored on your hard drive and it is referenced when you run the app the second, third, fourth time you run the registered app. Steve Cooper
