FFB not working

Hi everyone,i’ve been playing with a Logitech Driving Force GT and my ffb is not working in the game, like zero, i change everything in the options, reinstall the logitech game profiler, and still nothing, the only thing that happen was the center spring working but no ffb.
But in really slow speed(like 10mp/h) i can feel some resistance turning which is really weird.
If anyone know how to fix this please post below.
