This error should have been fixed a few weeks ago.
Try retuning the channels first and then select channel 1. Of it still persists try resetting the box by pressing the button on the left hand side 5 times until the box restarts.
You will though lose any recordings if you use a usb stick and also need to sign into your apps, like Now, again.
Let us know how you get on please.
