Whats wrong?

------------------ Solution --------------------
For whatever reason i commented out the following lines during an 
previous error, these lines needed, otherwise the supervision cannot 
find "devices" for the
sysmon module.

#    device(Dev::RemoteJoystick).
#        period(0.01).
#       can_id(0x100,0x7FF)
#
#    device(Dev::ExperimentMarkers).
#       period(0.1).
#       can_id(0x1C0,0x7FF)
