MattyBoi3

I have recently installed BF3 from ZLO and i followed the instructions to a T, installed everything required etc. and singleplayer works perfectly, but when i try launch the multiplayer, the "ZLO Launcher" window pops up, i put my ZLO account details in, and when I click "connect to master" it takes a little while then it says cant connect to master. how do i fix this ? am i doing anything wrong ?
