Hi.. I'm having the same problem and it happened suddenly, just 2 days ago I could connect. I've been trying since this afternoon but can't get in

I'm trying to contact someone on the channel but NOBODY is answering. I really don't know what to do.

I don't even know what did I do to get banned!
This is sooooooo frustrating.. What? What should I do.. just leave it like that? forget it and never go in those channels again? Please please!
Desperated
