Troubleshooting[]
Sometimes things don't work correctly. One tool is the Blender Console which will open when you launch Blender (not on Mac OS).
YSFlight Script Shows an Error[]
When trying to use the Ysflight Import or Export script shows an error "Python Script Error: Check Console". Check the blender console window. You may see a message at the top that says "Checking for installed Python... No installed Python found." Download the latest version of Python 2.6 and you should be good to go!
