i have a kind of old cable box with like 3000 channels or whatever it is now and its cox. Everything works fine but when i try to get something on demand like a tv show or a movie it says "this future cannot be accessed at this time" or "please make sure your cable is connected properly". I know for sure everything is hooked up right because i reset it like 20 times and all the channels work and everything, but the on demand wont. It doesn't work for free movies and tv shoes or movies you have to pay for? Someone help please.
