@Anonymous User Welcome to the community. You've tried most of the things that would be suggested, and if it was working earlier today it may well just be a temporary issue pulling the listings from the NOW TV server. However if it doesn't come back soon the other thing you could try is a forced software update which has fixed the issue for some other users before.
To do a forced software update:
Press Home on the remote to take you to the home screen. Then do the following sequence on your remote quickly and smoothly
Home (x5) FF (x3) REW (x2)
If done correctly a Secret Screen will appear (if it doesn't, press Home to go back to the start and then try again). Choose Update software and allow it to run (even if it reports the same version as you already have).
