Are things working today? Let me relate a little and get some thoughts.
Yesterday morning I set-up the PVR Stalker NFPS add-on. I've been using the 9.0.20 add-on with IVUE, but wanted to give the PVR side of things a whirl.
Anyway, things went well initially. The channels and the guide (epg.ninja/nfpsf.xml) loaded. The guide looked black and white. (This will make sense in a minute.) It appeared, though, that the times and programs weren't matching well. I deleted the guide material but it would not reload. Hours later it finally loaded. The guide then appeared to be snazzier. It had colors, but when I loaded it, Kodi would sometimes crash. If the guide loaded, it would sometimes freeze or would not load the channels. I thought maybe the guide was being tweaked and there were some kinks. I deleted the guide database and decided to wait until the next day.
Today, I've tried loading the new guide, but it remains empty. The channels load fine but don't display the guide data either. Since I'm still new to the PVR aspect, I'm not sure what is going.
Many thanks...
UPDATE ====
It downloaded the guide, but I'm encountering the same issue. Most of the time, opening the guide closes Kodi. This is the only situation in which this occurs. I'm using a Fire Stick with Kodi 15.1, by the way.
