I had this trim problem also, the trim axis was swapped with my joystick since LOMAC, so this one I already knew how to fix :)
But these are different problems. I actually believe the FF going off is a driver bug as I have seem this problem with other sims, and it looks like only MSFF2 is affected. I just wish there was a way to "reinit" the FF system so this problem would not eventually ruin my flight. :joystick:
