My guide was out on a Fire Stick with Kodi 15.2 I've fixed it by changing the guide setting in the PVR Stalker client.
On Kodi go to
System:
Settings:
Add-ons:
My Add-ons:
PVR Clients:
Stalker Client:
Configure:
Portal 1:
Guide: Preference = Prefer XMLTV
XMLTV: Scope = Remote URL
Remote URL =h**p://nfpsf.********** or use h**p://nfpse.********** for less memory strain.
I also made a change in the Tv setting on the guide might help with Fire Sticks
System:
Settings:
TV:
Guide: Change days to display from 3 days to 1 and highlight Don't Cache in local database.
