IPTV how to set up

[rkeaneno16]

Hi guys

Just recently i was running a paid sub through plex on a nowtv box
But S-y being S-y they decided to do an update which removed all side loaded apps and rendered the box as a door stop basically.
I have been trying for a few hours trying to work out this IPTV set up so i can get my private subscription back.
Im running a vu+duo got the iptv player in but dont know how to add my subscription to the player.
Seems to be way over my head any help would be great.

Cheers in advance

Ps or can i add Plex or something similar to the receiver
