When I log onto the DCS online store there is no buy option listed under any of the modules. I do not have the Nevada test and training range so that is why the red flag campaigns do not have a buy option; but I have the A-10C installed and everything works fine with it. My DCS world has the latest update as well. These are the only products which do not have a buy option, does anyone have any idea why? Do you need the new Nevada map for the enemy within campaign?
