Well, I tried to isolate it to that. I started fSX, made sure DFW was working. I reviewed my scenery.cfg, all entries proper. I reviewed my FSX.cfg. No corruption noted, All simobjects entries sequential and correct. I then made a couple of airline code changes to the AFCAD with ADE. I made sure to compile with the original file name. Ran FSX, now DFW fails to appear, Addon manager indicates Active not in scenery library. I then went to 2 other FSDT airports LAS and LAX. both work. After shutting down the sim I rechecked scenery and FSX .cfgs all was normal, all simobject entries accounted for. after reinstalling DFW and retesting to make sure it worked, I modified the AFCAD for LAS , then LAX. Everything worked normally. DFW showed up like normal.. I can modify any FSDT AFCAD, with normal results, except DFW. If I modify DFW the scenery disappears, and addon manager shows active but not in scenery library.I've attached my FSX.cfg . Maybe you will see something I missed.
I just don't understand this at all
