Sentry Predator Locator

I recently bought this product new, but on clearance at a discount/clearance store. Thankfully, I only paid a grand total of $0.77 for it. When I went to install it, there was hardly anything on the disc, only 1.17 MB, which was enough to send me to the company's website. This is all it said: "searchhelp.com This Domain is Under Construction Please Check Back Later Powered by Misk.com." So, after some searching, I finally found under "Sentry Parental Controls" in Wikipedia this sentence: "Sentry Predator Locator was discontinued in December 2007." One might say, "How can I go wrong buying this at such a dirt-cheap price?" Well, I say that if you buy this at any price, from any place, you're simply paying too much. There's virtually nothing on the disc, and there is no website or service to go with it. Maybe the people and companies reselling them now don't know about this; I don't know. I just wanted to let whoever would read this know.
