737 panel by mackem greg

I hope someone out there..perhaps Mr. Greg can help....I've downloaded his 737 panel for fs2004...it is a very good panel...however the dll sounds will not losad with fs2004...Mr Greg does address this problem but when I try the solution[adding a line in the fs9 config file] it does not work....so I can't load the crew announcements or the taxi program....does anyone know how to get around this problem or Mr Greg's email??...it's a great panel...just want it to work right..thank you all
