Finally picked up my scanning probe, yesterday, and found no activation code anywhere in the box. Called LRH also, yesterday, and was informed that the code should have been on the invoice. My probe was online ordered from Lowes, and I do remember receiving email confirmation, on my purchase, but had accidentally deleted that email with a bunch of other messages. But it doesn't seem likely that such information (activation code) would have been on anything generated by Lowes, as it wasn't Lowes who fulfilled the order.

What to do now? Besides returning it for a refund?
