F8R not received

[XORadmin]

Unfortunatly this morning the I2C is not working anymore.
MIDI I/O DEVICE input and encoder are working fine.
I didn't change anything in the setup from when it was working nor moving the cables.
Midi DEVICE input and encoder from MIDI IO are working fine.
I still have:
Midi Expander MULTI-IO
Midi/I2C setup:

• NS->16N 1-16
  
• Hex:31 DEC:49
  

Mapping Setup:
I2C SCCV#0 > TRCK TRK7 EC1
...
I2C SCCV#7 > TRCK TRK7 EC8

Connected the F8R to computer to check it's still on LEADER.
I can order another cable if that would do it but I don't know why it would be a problem. It's a 5cm cable that came with the f8R and connection looks sturdy.
The only thing is it is close to the ALM case power.. in case there would be a problem there with those 3 little wires with no shield I could try to move it around in the case.
This I2C system is really picky 

It got to be 16n -> NS. Is that probably the issue? And keep in mind after changing these settings the F8R need to be restarted as it doesn't detect the I2C stuff anymore.

I hardly got any issues, especially not with the cables. The main issues I got are limitations with the 16N firmwares (partly behaviour and partly the low-level I2C stack itself) which can always be fixed with restarting the 16n device (F8R is a 16n clone)
