I'm receiving an Access Denied error.

I'm running Kodi Jarvis on Windows 10. I made a donation to IKS66.TV and it was confirmed (email&bank). I set a mac address (used my actual last 3 from my NIC) with the 00:1A:78 prefix.

I'm using the IP Stalker Plus add-on. I select IPTV66 in the menu, I use my donation # as my login/password and set the last 3x (XX:XX:XX) of my defined MAC and enable the Send Device ID. I get an 'access denied' error. I am not sure what I am doing wrong, if anything?

Could it be possible the MAC I defined is being used by another device (not mine, some other user)? I won't be able to flush and set a new MAC until 8PM EST...

What are my other add-on options??
