I just purchased PMDG 744 and love it so much but while i fly, alot of the time a loud bell comes on and wont go off. I have looked over all the systems and can't seem to find anything wrong. No warning lights flash or anything. Can some one help me out.

pressurization and air conditioning is all set correctly?

Double check the eicas messages and look for any RED warnings displayed. Flaps not set, spoilers not down and brakes engaged will cause this at least on takeoff. Best,Randy J. Smith
