Oleg, I registered a member, but I still can't see other games room in lobby , why??
Other games, as in games other than CAW, like Silent Hunter 4, Dangerous Waters, STALKER, or whatever? For that you need to know names and possible passwords for those games' rooms, then Join them. There are hundereds of game rooms on Hamachi, you don't get to see the whole list, just the ones you joined.
