Please take note that you need to add your specific broker server first to find it in the Broker list at the login window.
To do so, please head to " File -> Open an account " and check the Server list.
If you do not find your server in that list, click on the green plus sign on the bottom of the list, then type in your broker name and click on scan.
If the scan is successful, you can now see your broker server on that list with a green/blue symbol on the left.
That symbol means the connection is good; if its reg/grey, please click scan again.
Also, always use the "Open Account" function instead of the "login" function so you can always check on the server connections first.
After that, click on your server, so it's blue/selected, and click "Next."
Now type in your login data and click on "Finish."
