Good luck dealing with them. I used WinCNC for 4 years and although the software works fine, dealing with the company is a joke. After your period of "support" runs out, they will refuse to help you unless you pony up something like $400 more for another 6 months or a year (can't remember exactly) of support.
If you're like me, you only have a couple of questions a year when you add a new thing to the system for example. Nope, no help, buy a service contract. The manual is marginal at best, there's no forum of users or anywhere else to turn. Even when you do talk to them, it's like an imposition for them to help you out.
I don't have a probe so I'm afraid I can't help you with it, except to suggest if you have support with the thing, badger them while you can to get it straight. If Troy won't return your calls (he's the support guy), ask for Mike, he's more helpful.
My true suggestion is to dump WinCNC and go with Mach3. A probe's a probe, it'll work with Mach.
