Well the AoW3 build seems to be (for me atleast) 15842 and trainer is for 15813.
Only option is to wait patiently till CH Crew updates trainer to latest patch. I guess Aow3 devs did some small patches to game.
The version inside the game is different from the launcher the launcher is 15842. Hmm they caught up the inside is 15842 now as well.
