downloaded planes

  • Hi, I have downloaded a spitfire plane to add to my easyfly3 simulator and followed the install txt instruction, i.e. added the .wav file to the sound folder and the other files to its own folder in the airplane folder. However, the new aircraft does not show up on the aircraft menu when I load the program. How can I get the downloaded aircraft to load and work in the easyfly 3 program? :) please. Thanks in advance.
