Hey Arma 2 crew, so i start playing Arma 2 and its the best action-realistic game ever. Better then other ego shooters and action games. I startet playing multiplayer 1 week ago, it worked perfect. Now i got a weird problem. When i press Multiplayer in the mainlobby then it tells me the message about online expierience can change etc... and then i press ok, then it loads (recieving...) then my game freezes and stops working. I dont hear any sound just a freeze. What is my problem? I test to remove my internet cable out of my modem and then pressed multiplayer again , then it worked (I was able to see the server-lobby). I just move the cable again in and the game freezed directly. Something is blocking? I tried to clean caches with ccleaner and tuneup but didnt worked. PLS HELP ME :) thund3r
