For me, press green, scroll down to IPTV add, open it.
At the top of the screen, your username and password should already be stored.
If not you're jiggered, if so press blue button to validate your iptv, it goes off and dies it's thing for a couple of minutes.
Then exit out all the way, press TV button, and ALL your different sections should be there(entertainment, sport, vod, etc
