File is identical and the trainer for version 1.3.1 works for the current (1.3.3) version of the game. Are you sure you selected the classic Dead Pixel game mode and not one of the others? Have you tried out on a new save game?
Disable your AV, run trainer as admin and read instruction. Activate trainer only ingame and WAIT for the SECOND sound (during progress, the trainer seems to stop responding but just wait for second sound).
