IPTV newbie

Cheers lads, many thanks.

Got my 3-month iptv66 sub yesterday just to try it out and then spent a while faffing around trying to set it up on my Shield TV w/ SPMC (Kodi) + PVR Stalker.
Gave up after a few attempts as the wife was grumbling about not being able to use Netflix while I was doing this - I retreated to the den where I installed kodi 16.1 Jarvis RC2 on my PC and tried to set it up there. Got confused over whether I should use 78 or 79 in the MAC address, chose 78 eventually, but kept on getting Stalker Authorization Failed messages.
Just after midnight I realised "Ahhhh, maybe THAT's what I'm doing wrong" (I never Reset my MAC) so went to https://iks66.tv/main/search and got told I'd used too many searches and would have to wait 24 hours.

I've no problem waiting until tonight before taking to the fray again, but I've a suggestion - increase the initial number of attempts for first-time knuckledragging klutzes like me :)

Cheers!
 
I had stalker client working kodi 16. installed a vpn, used different locations everything worked. now, I've done all the trouble shooting, donation checker, using epg updater, entered all the settings still won't work. Is my mac blacklisted because of those ip address changes? if so how do I get it working again. I have tried changing the mac but it's the same auth failed
