I have the same problem, can not run biz server, my account is blocked.
Your account is not blocked. There is no one connection of your receiver with the server.
BIZ... Why are you talking about back-up server, when your main server is ...8.org?
You receiver (emulator) must connect to the main server, back-up is reserve server in case of the main server failure.
I think, that you as well as
kuliboni have to pay attention to your firmware (maybe, update or change?)
If you have similar issues, it speaks not on the server problem, but on your receiver (or firmware, or emulator, or whatever it may be).
