Cant connect to master but the singleplayer mode works perfect. what can i do???

Someone knows how to solve that problem?

Try to reinstall client from here and replace again, same for launcher.dll http://zloemu.org/files/bf3/Client.zip

and check your password or email

Use zloemu mail+pass not zlogames

Update damn launcher.
