Reboot PC to clear excess memory, get a fresh copy of latest trainer and extract it. Run trainer as admin, read the instructions and try again. At times, a new game may be needed to resolve failed options if the data in your save file was altered. Use on a new game and test the option. If it now works, quit to main menu and load your save and try it again. May also need to run the game without the trainer first and play a bit so the save file gets updated to use possible new values.
If not file a report, not sure if that trainer can be updated anymore, 0x90 would need to see if we still have access to that version of the game to do so.
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.
