I have not tested these files for quite a long time, but are posted from Crazed 2.0's stash! See this for an explanation:

Summary:

Active Portal - the server that you got your donation from

Server # - Your assigned server number. If Rocket or IPTV66, USE '0'

MAC Address - the last three hexadecimal groups from your linked MAC. You may have to do an IPTV Reset on the donation checker if you don't initially connect

Time Zone - No need to make changes ... it isn't used. Your guide depends on your device settings, not Kodi or the addon.

Donation - You received this, and is used as the login/password to the server. Don't confuse this with your Order number

XMLTV File - Select the length of time for your guide. Use 24 for low memory systems, 72 otherwise

Connection Timeout - Use the lowest time possible to efficiently connect to the server.
--

If you have connection problems, first disable/enable TV on the system settings page, and then try clearing data.
Failing that, adjust the connection timeout, then do a IPTV Reset, or a MAC change to your donation.
Last, reinstall the add-on, or start from fresh in Kodi.
