hey, I've moved your topic because it was in the wrong place.
When you say "i can't join everytime"... you mean join a room on gameranger, or join the game in aom once it has been launched?
Maybe you see other players in italic when you can't join??
Give us more details please...
because it could be firewall problem, or IP problem, or port problem....
PS : mind to read the other topics... there are many tips : http://aom-gr.forumotion.com/technical-help-f7/
