A subscription is required to view this program

I just installed a new mini box and when trying to access any channel, a prompt comes up on the TV saying a subscription is required to view this program although I can hear the audio of the channel. But, I don't have this problem on my regular cable boxes on other TV's in the house. Also, the TV guide on the mini box is not listing any of my other channels besides the local channels. I have even tried doing a channel scan.
