Oops! We're sorry to hear that but not to worry. It could just be the cable or the USB port itself.

• Use the supplied USB cable or a known working cable.
• Restart your computer and try different USB ports. 
• If you have a Fly12 CE, turn the unit on.

If none of that works, it's likely due to the card you are currently using. Good news is, it can be fixed by simply formatting your card. Since it is not recognised, you will have to format it using an SD card adapter. You can follow the video instructions on this link here.
