I have recieved an e-mail to buy a new license, but in License Terms there is something like that:
[b][u]The product can be used for unlimited time after purchase[/u][/b].
The license entitles the user to move the program onto another computer that
belongs him. Software [url=]activation[/url] over the
internet is required (it is possible to activate the program on the computer
which is not connected to the internet, see [url=]manual
activation[/url]). 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.
