You sure you did the mission that rewards it? I use the trainer and got it just fine after completing the mission. It could depend on the options used though. I only use the infinite items and waypoint teleport.
If you have it, could you share it. As i just put 2billion lol but now it says error, so i lowered it to 25k and still says error.
Did you have Easy Craft enabled on after you completed the mission? Make sure to turn it off because the game won't give you the reward (like tools or the wingsuit) since it thinks that you already have it.
