Multiplayer problems in Operation Flashpoint!!!

[para]

I have installed Operation Flashpoint ( Full version ) and then added a No-CD patch. Everything seems to work ok, exept for the fact that no games appear in the multiplayer section, when I want to join a game?
The installation is from ISO from Deviance and so is the no_cd patch.
Has anybody else had the same problem??
Has anybody a sollution to this??
