ANother edit: Sorry it took so long. I hate working.....believe me.
Have you updated Kodi to version 15?
How long are you waiting for it load?
Sometimes you have to wait 20-30 seconds & the times do vary. Also,try to close Kodi again & then opening it back. That's part of the new 15 build, which does sometimes NOT save the input that you put into the Kodi settings themselves without editing the xml yourself. Remember, Kodi 15 is in a "still in progress" mode, per-say. But it does work better with this server.
If your still having problems. Try clearing the cache under the "System"/ "TV" / "General"/ "Clear data" : Mind you that this will reset the setting that you just put into your xml file. So you will have to repeat the steps above.
