You need to connect to a valid demo or real account in order not to get a no connection message.

So make sure that you are using the correct account credentials, account number, password and broker/server to connect.

These are sent to your email upon creation of a new real trading account.

Then either your broker is doing some maintenance, being Sunday, or you still have the wrong credentials, check your email for those.
