You should create different posts. When you gang up, it is hard to sort through the issues.
Larry - If you haven't gone to the Donation Checker to do an IPTV Reset, do that now.
DJ - You need to disable IPTV Stalker, make sure no PVR's are enabled and exit/restart Kodi. Now, open IPTV Stalker Plus (do not enable it), go to the configuration panel and click Defaults. Next, configure the disabled IPTV Stalker Plus with the appropriate information. Go to the Donation Checker and do an IPTV Reset. Last, enable IPTV Stalker Plus...and the channels should load.
DZ - I don't have any idea what app/add-on you are using. If the aforementioned information applies to you, go that route.
