I'm sry but sadly the trainer crashes my game.
1. I run the Trainer (Admin mode)
2. I run the Game
3. I load a Singleplayer World
4. I wait until game finishes loading and i can see my Oxygen/Energy decreasing.
5. I press "F1". After 5-10 Seconds there's is one "Trainer Activated". I wait a little bit and if i than do anything, like choosing a tool or block, game crashes.
Edit: Sry, i'm not able to get a debug information for you. As soon as the game crashes, the trainer seems to freeze to and i can't click anything. If i than close the game, the trainer resets.

Looks like it got patched again which is probably why it was crashing. The team behind it seems like they are interested in rapid builds so you might go without a trainer for a minor release or two.
