Did you use the options according to the instructions provided with the trainer?
Numpad 1: Capture Player - when you are in the game and can move around,
press this key to capture your character and then the rest of
the options below will work.
Numpad 6: No Enemy Collisions - toggle this on and most things pass
through the player. You are never 'hit' by the enemy
creatures, removing the annoying and slowing down
part of the game where your character is hit and there
is the damage animation.
Of course I did.
