I have a question about buying it by downloading it, I have sometimes tried to buy a game (or movie's, tv shows) by download but it says that I need to be in the USA to download them. I would like to know if when downloading the game directly from stardock (through that stardock central program) it checks your computers IP address to see if your in the USA or if I can download it from anywhere(I am in Mexico right now). thanks
