I've changed from "the little black box" to a fire stick, is it possible to reassign my my donation to a new mac #. I have tried to do this at http://iks66.tv/main/search but it tells me when I try that mac cannot be changed at this time.

I'm running windows 10, newest kodi {jarvis 16.0}, iptv stalker papaio and every thing works great.Just need some guidence on what epg that works with this setup. have tried a few but not having much luck. Any advice or direction to a guide would be appreciated. Thanks
