Camera Won't Record Anything

I recently acquired an Apex x100 drone and have been trying to get some video from it. I press the video record button on the controller, lights flash continuously on the drone, everything seems to be working, but then when i go to put the sd card in the computer it says that there are no files on the card. Is there any way to fix this? I've tried filming with and without the POV Screen connected to the remote and still nothing.
