Before you attempt to log in to any of No Magic's servers, you must:
Have the user account on the server.
Be sure the server is running.
Be sure the server and the client application use the same Java version. Small Java version updates may differ.
It is alright, when server Java version is 1.8.0_45 and client Java version is 1.8.0_51.
To log in to a server
From the Collaborate menu, select Login. The Login dialog opens.
Type your user name and password.
Provide the server address and select server type.
If you want the client application to remember your credentials and automatically log in next time to the server upon starting the client application, select the Auto Login to Server check box.
If you need to connect to the server using the SSL connection, select the Use Secured Connection (SSL) check box.
The SSL connection must be established on both the server and the client side.
Click OK.
Wait while you are connected to the server, and then you can start performing collaborative tasks.
