There has been no update for the game for me and the current trainer works fine.
I re-downloaded and it worked. Odd, seemingly it is the same version trainer as I had before.
Apologies for the false report.
Anyone having issues using the trainer lately? it seems to crash alongside the game.
You're not the only one experiencing the crashing. But it resolved itself at least on my PC. The game has been updated, so the trainer no longer works.
