I may have committed the unpardonable sin - without realizing the consequences, I deleted all exclusions that showed up on a "Load Stock Data" for airport AXAS (Altus/Quartz Mtn) and now cannot remove stock generic buildings or scenery objects. How do I get back to square one? (reload ADE 175?, reload FSX? All other airports are working fine. All changes and compiles look good in ADE but stock buildings still show up in FSX. This is my first post so I hope I have not committed any other sins I have read all the post I can find but nothing suggested has helped.
