Hey @wofuman Somone is Creating one if it says that, I had that problem before and it was because yes the person was making the trainer, so My Suggestion for u is just wait for the trainer to come out.
Game was released years ago. SWKOTOR 1 has mod already. I also found a post that says the same error but its a different game. They say that the game has multiplayer that’s why they don’t support it. This is a SP game hopefully, they really are creating a mod for it.
