Because I am tired of repeating the same thing over and over, I am putting this information here so we can just simply point to it over and over instead of writing and saying the same things over and over.
This game has an active scanner that checks the game code for changes and modifications, especially when you enter battles or end turns. if you have any trainer options running when you do either, likely the scanner will detect your trainer and crash the game.
which is why months ago we added the following option:
Numpad /: Options Off - turns off all options. You know options are OFF when you hear DEACTIVATED. Press again to re-enable the trainer (Funds, Skills, XP and Rank options cannot be used while trainer is deactivated). Use this before entering battles or as an easy way to ensure the trainer options are off before turns. Trainer is in ACTIVATED mode automatically when it first starts. If certain options are not working when pressed make sure to press this key again to hear ACTIVATED to allow them to function again.
if you actually READ the instructions and READ what others have posted here dozens of times, you will see that you need to use this option to turn off the trainer before you go into battle or end turns. after you have left the battle or the new turn is ready, then press it again to re-enable the trainer and then you can use your options again to do stuff.
if you don't follow the trainer instructions and leave options on when ending turns and etc. you are going to have problems
now i how this clears it up for the last time. don't blame us for the protections that developers have put into these games.
