Hmmm...that kinda sucks for an answer from Demco; they buy the business and then abandon previous owners, albeit a 13 year old product (if its still working, that's good to know)
I have a new Stay and Play Duo, I will say this they do have excellent support for the new product. That's why it's kinda of surprise they are hanging you out to dry.
