i cannot seems to be able to delete unwanted channels.when i hilight a channel which turns orange and i press the blue button for delete,nothing happens.also i have VPN by Private Internet Access.when i first got it when connected, it would say connected,but then i started to see authentication failed.so i generated a new password from Private Internet Access site,but it is still saying authentication failed.i have reset my router and when wireless but it still says authentication failed.how do you know when you are connected?most of my apps works great but one like iptv and gotv etc does not work for me it needed some kind of plugins.i am still testing trying to get some apps to work thanks
