After adding all of those airports and landing strips, I spent about two days troubleshooting to eliminate errors that threw up warnings every time I launched X-Plane. The last one I was to eliminate was caused by THE-FAIB Aircraft Library. I finally discovered that there were two zip files within the directory structure that had all of the aircraft. Once I extracted all of those planes and deleted the zip file, I was fine. The rest of the errors were solved by finding some add-on libraries that some of the airports depended on, etc.
