This app has been working great now it stinks

I use this app to record tv shows so I dont have to bother by husband when he is watching tv. Up until now it had been great. The app could not be used tonight because there is a lot of blank spaces where tv shows should have been. I deleted the app and reinstalled still the same problem. Please fix. It was is much easier to set recordings with the app then on the tv.
