I have recieved an e-mail to buy a new license, but in License Terms there is something like that:
The product can be used for unlimited time after purchase.
The license entitles the user to move the program onto another computer that
belongs him. Software activation over the
internet is required (it is possible to activate the program on the computer
which is not connected to the internet, see manual
activation). Free updates for a year, paid
upgrades (second and subsequent years) with a 40% discount. Free technical
support for the life of the product."
Does it mean that you changed License without informing users? It's a shame.
