hello. new to siming. I have xplane 10.40 and found plan g 3.1.3 on web and installed. however, when I click build database it brings up selection of sims but all are greyed out. tried running as admin but no change. I have also opened xplane and connected to squawkbox and retried but no change. cannot go any further. any help would be greatly appreciated and my .net is 4.5 if that makes any diff.
