Crossfire - bad game

Plz fix crossfire, today i was on s&d match then it says failed to contact the host server (bad error, i didnt lost connection, i got no firewalls dont hav a ntivirus ;/), on eagle eye, i was 27-10 score, 12-12 (remains 1 round, 390-400 exp), then this error happens to me, omg crossfire, i cant level up on this lame game

When i log in to crossfire, i need type my details fastly cuz, if login windows is more than 30 sec ative, it says failed data transmission

When i enter a room, most of the times, it says host error, then i go back to lobby ;/ wdf z8, fix this game, lose 390 exp, when remains 1 round, is bad
