you might need to remove aerofly completely,,,remove it from all programs,,,then click on drive c ,,,open program files find ipacs and delete the ipacs folder,,, restart your computer,,,and reload the program,,,then go to aerofly pro dluxe website and download the appropriate patch,,for whatever version youre using,,im not an expert ,,but any ghost images or remmanants of any old or corrupted files will cause a conflict ,,in some manner such as display or running the program or individual components of the program ,,like calibration,,,lastly make darn sure you have the correct adaptor,,some only will respond to a stereo or mono style plug,,even if the program senses the dongle or transmitter....
