MM server disconnect

Hello. I'd like to ask if anyone has the same problem as me.
So first of all, when i open Cross Fire launcher, when the "Steps" start it's really slow.
After a long waiting the game opens, i type username and password and when i click on a server it slowly opens but i can't get in any channel.
I get this : MM server connection failed
Anyone can help me? I think it might be my network but i've played today without any issues and antivirus is turned off.
