Payloads not running

[hacknbone]

I have recently update the firmware to 1.6 but I am unable to get any payloads to run. 

Payload.txt

DEBUG "switch-1-debug" "Hello from debug extension!"
LED SETUP
ATTACKMODE HID SERIAL
RUN WIN notepad.exe
Q STRING Hello World
LED FINISH
DEBUG "switch-1-debug" "Bye from debug extension!"

after running the payload on switch 1, I get the following message in syslog

Any help would be great.

This makes me question whether the RUN extension is installed. 

I would recommend a simpler validation payload, such as 

LED SETUP

Then incrementally add to the payload, such as ATTACKMODE, QUACK, etc.
