Example_control_loop doesn't seem to work

I’ve been trying to test this example given from the RTDE example. I’m running it as a Daemon like I tried with record.py (which worked well).
With record.py, I checked the input/output register used and they never change, always at 0 on the simulator…
If someone had the same issue, please help me to fix it …
Thank you.

(I’m using version 3.5.0 and sdk 1.2.41)
