Having trouble with HopeRF RFM95W #12

This is the error received when attempting to run test_lora.py

I'm using a raspberry pi zero, and have the pins as described, with 3v3 -> 3.3v, all the GNDs going to separate GNDs on the Pi, SCLK -> CLK and CE0 -> NSS.

/home/pi/pySX127x/SX127x/board_config.py:51: RuntimeWarning: This channel is already in use, continuing anyway.  Use GPIO.setwarnings(False) to disable warnings.
  GPIO.setup(BOARD.LED, GPIO.OUT)

Fixed it by taking everything out, and putting it all back in again. The IT Crowd "Have you tried turning it off and on again?" comes to mind.
