I am also having issues with the trainer crashing the game. The game will run fine for a while and randomly crash. I only use god mode and no reload, since unlimited ammo doesn't work.
I use aurora. And before it's asked; yes I run both as admin, it was installed correctly, I have uninstalled and re-installed both the trainer and game, and I have this issue on the RE4R trainer also.
I would suggest putting in an update request if you have an issue with the trainer
Please use the update notification system to report a game patch, update or to report that the trainer may not be working with the latest version of the game. If 3 or more reports have been filed, consider BOOSTING the priority of this title for a faster turnaround on the updated trainer.
