EasyProbe error

I'm trying to get EasyProbe running on my mill. I had an older version running, but am having problems with the probe signal.
The report file shows: Probe_postgui.hal:14: Pin 'hm2_7i96s.0.gpio.040.in_not' was already linked to signal 'probe-in'
Probe_postgui.hal has:
#

---

Probe signal and LED control (see readme.md)

---

# dbounce_probe.in must be linked to the probe tool input of the interface card
 
setp  dbounce_probe.delay      [PROBE]DEBOUNCE_TIME
setp  xor_probe.in0            [PROBE]PROBE_SWITCH
 
net   probe-raw                dbounce_probe.in             <=    hm2_7i96s.0.gpio.040.in_not
net   probe-switch             dbounce_probe.out            =>    xor_probe.in1
net   probe-signal             xor_probe.out                =>    motion.probe-input pyvcp.probe_led

I can't find any other instances of probe_in. Where might it be?
