Pls help me

You are banned from CA-EU o_O

That was completely wrong statement that made no sense. If he would be banned, then it would show the message which says that.

I know, try to send a ticket to CA-EU. They will help you out.

Or try this:
- Turn Firewall off
- Check your connections, ports etc

Or have you changed any options in your internet settings that doesn't allow packets from CA-EU anymore?

Just send a ticket.
