B727 problems with panel and airfile

Anyone know why the latest and greatest airfile by Charles Fox (4 years of work) won't let me use the Rudder on it's intended 727 model? Is there a rudder lock?
Also a Richard Probst's panel question... I've tried everything to get rid of the most annoying L O U D cockpit whining. It sounds the same as the sound "rp727_2_400hz.wav" which is in the panel folder, but no amount of removing it or renaming it will stop the infernal racket. If I remove the panel .gau file called "Rp727_2.gau" it solves it, but alas then I have no gauges
