Hello there. Same thing happened to me. Tried all kind of variations. Tried install seasons as well. 1 Picture example of default airport. Plane not lined up on right marks where it should be. Maybe this is the reason. 2 picture is KSFO from MisterX and just old autogate plugin work. Also I found 2 tabs in plugin menu. is it how it supposed to be? I did delete SAM plugin and custom scenery library. Installed, activated, than droped link from resources/Sam/libs to Custom Scenary folder manually. None of it worked. I hope you guys can fix it soon or give us some more clear instructions of how to make this utility to work properly.
