The trainer works fine whilst playing in the main game and doesn't make any difference whether it is run in admin mode or with antiviruses on or off etc.

Has anybody managed to fix this issue?

Thanks

I Didn't turn on Super Strength and it stopped my crashing and game hang ups.

The only option that I have used is the unlimited health, but the game crashes if that is used the moment I attack Harley's goons.

The game crashes as long as the trainer is activated, even without activating any options within the trainer, at the same point, which means that the trainer is seemingly incompatible with the DLC.
