Everything starts off fine, but when coming into final approach the engines roll back to idle. Im fully configured for the ILS landing and approach mode is armed, but a few miles short of the runway the engines roll back to idle and when I disengage A/T in an attempt to prevent the plane from stalling the throttle levers move in the sim but it doesn't register with the plane. Then the plane hits the ground and starts to spazz out. I bought the 77F through the store in MSFS, it says it is updated to version 1.0.14, and I have the new "salty-747" and "masterrob94-salty-777" mods downloaded. What is the issue with the plane on the final approach? 

Good day!

Anyone here had a problem with approach mode? The localizer is armed and aligned but when I click the APP button to arm the approach, nothing is happening, there's no green light that will appear on the button and on the PFD, it is just "LOC", there's no G/S. It is because I didn't set the frequency? I can't seem to find where I can set the frequency for the ILS because the knobs is INOP on pedestal and it looks like that it's automatic just like on an Airbus.
