Trislander door warning

[GWSimulations]

I've just downloaded Marcel Kuhnt's excellent FS2004 Trislander.
It's a great aircraft, but is there any way to disable the door warning alarm sound. It is very annoying, and it just won't go away.

Please help.  :'(

Is the door shut? Press Shift+E to shut it..

Either that or turn off the sound..

A- open door and close again

B- the sound could be stuck on a loop, press Q twice to turn it off and on again - works sometimes

C- find the annoying sound's file and remove from sound folder

hope this helps

I've tried A & B, so I'll try C.
