Can this trainer not be updated? Did I pay for Unlimited only to have shoddy or nonexistant support on these trainers?

Its difficult.

Just because your favourite game is not getting updated anymore doesn't mean we offer shoddy support. There is not enough hours in the day to do everything.

And it is the current generation of players who seem obsessed with updating when they can (except for those on Steam who have close to no say in that), I only update a game if it needs updating.

Works with and without mods installed as well.

There are some engine limitations that can come into play if you have too many mods installed or too much action at one time will cause a CTD, but nothing like you are describing with crashes after pressing the F1 key.

Or better yet, make older trainers free. Since, y'know, there's no guarantee they work anyway.

Or better yet, we can retire the game and simply remove all the trainers if "they're not guaranteed" to work since you're ungrateful to the staff for trying the best they can with an aging game.

For the few people reporting problems here, there are many other users using the trainer properly suggesting the problem is on your end and that you're not properly troubleshooting your game and trainer.
