Ok, first thing... completely uninstall Kodi. That includes the user data when prompted. That should get rid of all the extra stuff that may be left over when you do the next step.... Download, and reinstall Kodi 15.0 from Kodi.tv
This should get you a clean copy of Kodi. You can add other addons later. PVR Stalker i.e. "Stalker Client" should be there built in. Configure that using the tutorials with you properly linked MAC and the proper server. You can set up the EPG as well, but its not fully operational today.
Enable the addon from the add-on information prompt, and exit out to home, select Sytem, and find "TV" or "Live TV". Clear Data from the main page, and then "Enable" while you are on the first page. Here is where you will find out if you'll load or not. If you don't, you can use the modified PVR Stalker with an extended timeout, but it shouldn't be needed.
