Sorry, never had any issues with the trainer except the problem with the G-Virus bossfight.
trainer was made to work and was tested and the function being altered was for the base version of the game. If there is 20 other 'sensory' functions added to the game for 20 other DLC episodes, then it's possible that the option only works for the main original story.
Sounds like you were RE.net banned. Check your email.
Also, it doesn't seem like the unlock all trophies etc stuff works for Ghost Survivors content.
