I have been trying to get my HBO Now to load for a couple of weeks now to no avail. I have tried updating my TV software but I am on the current version, which shows as version 1280. I tried doing the smart hub reset as well as the full factory reset, but the app still won't load and I continue to get error 118 when I try and install it.
Every other app works just fine, I even installed HBO Go perfectly fine, but for some reason HBO Now won't install.
It might be partially installed, try going to the menu in the apps menu it should be in top rt hand corner, than go to all apps. See if HBO go is there, if so try uninstalling it, than reinstalling it. Before reinstalling it I would turn off tv , unplug it to reset it after about 30 sec. Than reinstalling. See if that helps
