Hotkey failure is usually caused by missing administrator privileges, interference from the Fn key, or conflicts with other background software (such as input methods or screen recorders). To ensure that the trainer can successfully intercept keyboard input, please run GameBuff with "administrator rights." Quick Solutions: 1. Run with elevated privileges: Right-click the desktop shortcut and select "Run as administrator." 2. Fn key lock: Laptop users, please check if you need to press Fn + the hotkey simultaneously. 3. Check for hotkey conflicts: Close other applications that may be occupying the F1–F12 keys.
