Enviro + air not working after installing code

I recently got the enviro + air quality, and Im having trouble getting it started. when i first installed the one line code, it aborted itself, so i updated rasbian. after, I installed the sensor board on the pi, the screen flashed and turned off, and I re ran the one line code. It installed, but the screen on the board is not showing any data or turning on. Even after restarting and re plugging in the board, i still see nothing. Im not sure what Im doing.
