I'm back again with the same problem I started having with FSX before I kicked it to the curb. Now I've had my computer completely revamped: new mother board, new solid state drive, new processor, new program (Prepar3d v4). My version of ADE is 1.76.6715 and, just like before, when I compile, no changes are made to P3D. I get no compiler error messages and when both programs are running I can see the little "x" in ADE marking the aircraft that I'm using slewing around the airport. My guess is that it's compiling to the wrong folder. Currently that's: C:\Program Files\Lockheed Martin\Prepar3d v4 SDK 18.104.22.16820\World\Scenery. This was the path chosen for me by the ADE new user wizard. I've also tried other paths with either the same result or a message telling me it can't compile to that folder. Anyone have an idea to what I'm doing wrong? Thanx.
