Error accessing GPIO

I am running HASS through on a RPI 2 that was installed with the AIO installer. Connected to the GPIO pins, I have a DHT22 and rf transmitter. I am able to use the GPIO rf without issues, but the DHT22 is not able to be read. The error in HASS is:

  File "/home/hass/.homeassistant/deps/Adafruit_DHT/Raspberry_Pi_2.py", line 34, in read
    raise RuntimeError('Error accessing GPIO. Make sure program is run as root with sudo!')
RuntimeError: Error accessing GPIO. Make sure program is run as root with sudo!

I can read the temp/humidity through the command prompt without issue. The hass user is already a member of the gpio group.

pi@raspberrypi:~ $ groups hass
hass : hass dialout video gpio

Any suggestions are appreciated.

Perhaps this will fix your issue.
