I would like to obtain the donators version, but when I open my SimHub and click the Paypal button, nothing happens. I have not found information about how much they are asking for a license, and if this license is forever or not. No information on the program, on text files, on any webpage... I do not find the extra goodies of the donators version totally neccesary, but if the license is not expensive I will buy it, because I really enjoy this program and I will be happy to contribute to its development. PD: I have a license for Sim Commander 4 (for bodyshakers). I suppose this license will not be usable for SimHub. Are these programs made by the same developers?
