If you can't see the Server List on Client, then you have missing IGC.DLL/ServerList.bmd file from Client folder !
Reason: It happens is because Windows 8 and + users, the programm Windows Defender automatically deletes that file.
1) Turn off Windows Defender !
2) Turn off other Anti-Virus programms (maybe Firewall as well) !
3) Re-Download Client again from Downloads
