A few questions came up and I will try to clarify things a bit:
In the default setup, gizmo will pop a little screen every time you start it up. It will ask you to refresh your license, so it loads you up with a full two weeks of "possible offline use". We do this so no one can say that "gizmo phones home behind my back without me ok ´ing it".
If this bothers you, you can opt out of this "automatic refresh on startup" (go to the preferences box). Gizmo will then count down your two weeks silently, and ones it runs down, a window pops up and asks you to refresh your two weeks. This is exactly the same process that would happen every time you start up if you hadn´t opted out.
The third option is to bring up the refresh box yourself and trigger it manually (if you opted out but plan on going on a trip without internet access, for example).
Once your two week timer runs out, the box pops up - and you need to be online to refresh it. If you aren´t you can´t use the program until you are online and can validate again. This is exactly how X-Plane (digital version) does it, too.
If there is strong demand to do ALL of this without bothering you (i.e. phone home to refresh silently), it may be possible to add an option for that to the preferences menu. Just let us know.
Cheers, Jan
