For how long are free and pro versions valid?
From Tweener version 0.3.3891.9201 on, the whole licensing system has been
completely overhauled and
simplified, to match with my upcoming plugin for heat and insulation simulation.
If you are offline, you only have the functionality of the free license Tweener, and
it expires about a week after publication. You might be able get a new week by updating to
a new version if there is one.
The week is baked into Tweener - it is counted from the date of publication,
not the date of
installation. The purpose of this system is to encourage you to stay updated.
If you are online, and don't have a pro license, the free license Tweener is valid
for about a week after the date of installation (not the date of publication, as in the offline version.).
If you are online and have a pro license, it will work and will be valid for about a month on as many
devices as you like (but you have to get the device names for each device, as explained below.) Each
device needs its own activation code.
