Hi,
You can use the renew link to get additional time on your license if your license is not on autorenew.
In general the license is not transferrable, though all licenses allow you to activate at least two computers.
The subscription/non-subscription licenses are in your online cloud account. In general if you activate a computer it will apply the subscription first until it expires and then it will go to the basic licenses if there are no active subscriptions available.
