Same story, after upgrading to Jarvis trouble with Stalker. I think I am using the right server address, etc. that is the only thing I have changed. The Stalker logo changed so I think am using the new Stalker Client. I can get the channels and they play, but now I am getting 'Authorization Lost, re-authorizing', then 'Re-authorized', over and over and over every 10 secs or so. Even when I am not watching IPTV. Any suggestions?
