Interfacing probe help request

[1hander]

hello dave ... i have a new problem that is not msm related but im hoping you can help...
i just got a new probe but i cant get it to work... i keep getting probing error..

the funny thing is that if i remove it from the spindle i can trip it by hand and its fine... i have tried switching to active low... but no use...
i try using a potentiometer and adjust it till i can get the probe to work but i will only work for 1 or two cycles..

i just cant figure out how to wire it.. help if you can

I'll need some more detailed info before I know if I can help.
What is the make and model of the probe?
What BoB are you using?
How is the probe currently wired to the BoB?
Is this a parallel port system or ?
