Strange, I'm seeing a different MAC address as well, v1.87.
I'm seeing two different MAC addresses, on the main TV Online page, and on the Settings page. I changed the MAC on the donation checker to that which was on the main TV Online page, and that got me connected.
Mine has always shown a different mac address on the live tv screen. Don't really understand why, but mine was working fine earlier this morning. V1.87
it first one in server setting and if you get MAC already exist need take a picture and all your info and send it to a super mod they are working on two mac but still its first one in server setting
