I tried Instant Scenery a few years ago but never really liked it. As you are using ADE you don't really need Instant Scenery anyway as you can place models and library objects using ADE. I released a large airport package at the start of this year and placed over 200 individual building and vehicle models (most created by myself but I did use a few 'stock' FSX items) and all model placement was done in ADE. Here is a link to some screenshots of my airport to give you an idea of what you can do with ADE once you get the hang of using it.Good news I got it to work.Just a simple taxiway change but its a start.Now the bad news.When I use instant scenery 2,it crashes FSX.Any ideals on this.
