Moved from EPG subforum....
First, you don't have to work this alone. We do want you to read the how-to's posted in the stickied topics in the top of most of the subforums for the different add-ons and emulators, and if you follow those carefully, you won't be going through trying different 'rabbit holes'.
Second, you should pick one of those add-ons and get it going, vs. trying different ones. Since you can access the donation checker, your account is good, and you just need to configure your add-on properly. For now, I would recommend picking either the IPTV Stalker Plus 10.2.3, or the latest version of the PVR Stalker NFPS (20160510), as they are the easiest to configure. After you have properly linked a valid MAC (starting with 00:1A:78) to your donation/rocket number, follow the tutorials on how to set up either of the addons... not both. If you are still having issues, let us know, and someone will help.
