it looks like the guide is being downloaded properly but is not being configured in the stalker client. Going into the Stalker Client settings and changing XMLTV to "Local Path" it automatically populated the epg_xmltv.xml location. If it doesn't for you it is C:\Users\XXXX\AppData\Roaming\Kodi\cache\epg_xmltv.xml. Not sure if necessary, but i cleared data (Settings > PVR > clear data) and restarted kodi.
