No Screen Output - Troubleshooting

[jediempi]

I have a RPI ZW2 with a 64x32 screen. It is running MLB, NHL, NBA and a couple other boards without any problems.
I performed "git clone https://github.com/datagod/LEDarcade"

Next I ran:
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow

Now I'm running:
"sudo python3 RunningTest.py" = No display on led matrix, but I see the commands being run on my ssh session.

Also: "sudo python3 RunningTest.py --led-gpio-mapping=adafruit-hat-pwm --led-brightness=40 --led-slowdown-gpio=2 --led-cols=64 --led-rgb-sequence=RBG"

Both commands have screen outputs as follows:

--Load Config Data--
Config file not found! Running with default values.

Suggestion: to slightly improve display update, add
isolcpus=3
at the end of /boot/cmdline.txt and reboot (see README.md)

-- Starry Night Display Text
Text1: HIGH SCORES
Text2: WATCH THE TOP PLAYERS IN THE WORLD
Text3: BREAK RECORDS, MAKE FRIENDS, CELEBRATE EXCELLENCE
ElapsedSeconds: 2
ElapsedSeconds: 3
ElapsedSeconds: 5

Am I missing something simple?

Thanks!
