Can't access minecraft beta 1.2 console edition

So I tried to access my Minecraft beta 1.2 and it gave me a message saying "Give it another try"
I followed the command and I did it again and nothing happened, it of course said the same thing so I reset my Xbox and tried to access the beta again and then it said the same thing, so I come to report this issue because I have no idea what to do if any Mojang developers can respond to this issue it will be greatly appreciated
