A good evening I am getting very frustrated trying to set up this icebox that arrived last night. I have spent six or seven hours trying to get things happening. I have successfully connected it and put in my Wi-Fi password but no EPG is showing and no channels are coming up when I go into channels it's just blank and I don't know how to fix it and I can't get hold of anyone to give me some guidance and of course my question I cannot find the answer to in all the guide notes which is super frustrating help please someone thank you
