screen goes black in tv channels, HELP!!

Hi, when I click on tv channels for live tv. everything looks good, channel list is on the right, the preview screen is on the upper left, description below the screen. After I click on a tv channel. The preview screen comes up fine, the rest of the screen goes black, cant see nothing but the preview screen. I’m kinda at a lost. I am using Aeon Nox 6.0.0 any help on this would be great, thanks in advance…
