Worked on this with Jaks in chat, AOB script error, tried all the fixes but no go. Looks like a hotfix is needed.
There was a small update a couple days ago. Infinite Launch Thrusters currently does not work. There are currently 4 reported incidents waiting already. We'll have to be patient because this trainer has had to be updated a lot this year already. Right now Launch Thrusters may not be infinite, but recharging them is still free with a different cheat.
If you activate the trainer other than at the main menu it may cause other cheats to fail as well. Restarting the game may be required if that happens.
