Struggaling to get guide working

[Nuk3na 2]

I have a m3u playlist added and all my channels work i have paid for the sub at schedules direct however im an unsure on how to proceed i have added the login details to emby and selected GB and then one of the listings. I save it and grab new guide data but then nothing displays. Can someone tell me the process i need to follow and i see on schedules direct i can add line ups however GB isnt listed but it is in emby so i cant even add the one i select in emby to schedules direct if thats the correct method.

 

Any help will be greatly appreciated.
