When you buy Proxifier with a onetime payment, you get a perpetual license and free minor version updates (e.g., 3.00 -> 3.99). One license allows one running instance of Proxifier at a time, so you can even move the license between computers. Windows and Mac versions require different licenses. Please see Proxifier EULA for the other details. Elena kuzavini diedVolvo s60r mpg
