When you willfully use cheats, trainers, hacks and editors to manipulate the game in a way that in not intended by the developers, you run the risk of a corrupt save. Besides, are you sure it was the trainer and not the game itself? See a few threads on corrupt saves in the steam and Capcom forums, Also seen that Ultimate Marvel VS Capcom 3, Street Fighter IV and Dragon's Dogma just to name a few (all Capcom games) also had corrupt save issues. Don't be so quick to judge as it could just very well be a game issue. If the trainer was not working as intended you should have used the UPDATE NOTIFICATION system and stopped using the trainer until it was evaluated and if need be fixed or at the very least posted what the problem was to see if we could help you resolve it.
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.
