IPTV66 IKS66 renewal question

[rgturk100]

on the renewal form I am asked to enter my MAC address. Since I changed to currently using a playlist via IPTV Simple Client PVR, I have zeroed out my MAC and all works fine.
Should I enter my MAC on the renewal as 00:00:00:00:00:00 or use my previously user defined MAC 00:1A:79:XX:XX:XX that I used with the Stalker Client PVR. In other words which entry will make the renewal process work seamlessly. Thank you.

nope, just leave it blank.

Entering your MAC is only an option at the website.
You can leave it blank and your playlists will still be okay.
You can also blank it out yourself or add a MAC yourself anytime at the service website
