Troubleshooting Activation Issues

  • Failed Activation:
    • If activation fails, unplug the KMbox from the second PC, plug it back in, and try activating again.
    • If it still fails, your KMbox B Pro might not be an original device and cannot be activated. However, you may still be able to use it with limited functionality.

By following these steps, you can ensure that your KMbox B Pro is running the latest firmware and is properly activated. This will help you get the most out of your device.
