I realize there is a fix for this by uninstalling the airports and re-installing them with the Real Time Scan off, and excluding them from the scan. However, I have tried everything that has been listed everywhere online and I can't get it to work. I loaded up Flightbeam KIAD or FlyTampa's KTPA and they're fine. When I try to change my location to a FSDT airport, the buildings and couatl menu go missing. I can't figure out what I'm doing wrong. I have tried everything, including completely re-installing FSX. I have McAfee but I turned off the Real Time Scan for that and installed the airports with no scanning device on. I tried installing MS Essential and I was able to exclude all the files that have been listed on this forum. Still no luck. I have gone to task manager and made sure all the McAfee programs were not running in the background. Please help, I have no idea what's wrong. I had no issues like this in the past before this weekend (I haven't been on FSX for a few months). Thanks for any help!
