[smalllfly]

WHEN I TRY TO OPEN FMS, I AM GETTING AN ERROR STARTING PROGRAM WINDOW SAYING - A REQUIRED .DLL FILE,COLDET .DLL, WAS NOT FOUND. ANY IDEAS?

PS - I FLY REAL MODELS, TOO AND HAVE THE PREFLIGHT SIMULATOR ALREADY AND I "NEED" TO HAVE THIS RUNNING - THE WASHINGTON WINTERS ARE HARSH FOR REAL FLYING!
