ive played the last 2 days without a trainer and the game never crashes. today i thought about using the trainer and trying out ONLY the instant troop building option and the game crashes in the middle of the CPU's turn. and YES i pressed F7 before i ended my turn
The information you provided is effectively useless and in no way helps us help you. If you want assistance, provide useful information like: Game version, trainer version, which options do/don't work, and send a savegame to Caliber if the issue is reproducible. Try using an option, saving, exiting trainer and game, reloading save, and trying again. Try multiple options. Try reading the 12 pages of help before this one.
