Thanks for the response. This is probably going to be clear as mud but when I say I used my Community folder I mean it is into this folder that I loaded the unzipped aircraft-longitudefdefix folder per the author’s instructions. The thing is I have a FS2020 dedicated folder that contains folders: Community, Official, and Temp., all within a folder called FS2020. It is this Community folder into which I drop all of my modded files such as terrain, airports, etc. (so far with 100% success). The author referred to a folder directory path “\LocalCache\Packages\Community”, but again my Community folder is a stand-alone in my FS2020 folder on my dedicated drive. Also, per the author’s instructions, I DID overwrite my original default layout.json file with the author’s unzipped layout.json file. Obviously I miscued somewhere but I have not a clue. Hope this helps you figure out where I went wrong. I sure would like to get my Longitude back. Thanks in advance for the help.
