I am also having problems. I have downloaded the Orbx Library and was trying to look at the demo for Great Britain South for X-Plane but it doesn't matter which method I choose I get 1) Open in Orbx Central - Safari can't open the specified address, 2) Manual download - error 502 Bad Gateway, 3) Linux/MacOS download - error 502 Bad Gateway. How do I get the demo scenery? And how do I load it? Does it go in the Orbx Library folder? Where does the Orbx Library folder go, should it be in the Custom Scenery file?
Thanks for your help
