hdhomerun problems

I had hdhomerun set up and it was working great. My pc died and I had to build a new one and now when I set up windows 8.1 and media center when I setup tv signal it sees the three tuners for the hdhr but when it finishes and I go to channel in guide that shows channel what is on and click it, it says there is no tv tuner. How can I get that when it shows in the setup? Using a cable card and Cox tuner attached. Thank You
