this is only due to your internet provider problem, some players need to open certain ports for the game to make it work with others, call your internet provider and inform yourself about it, if they say its impossible, you will probably have to change your internet provider I am afraid.
sometimes digits like 1-2 just disappear after some time has passed, what 1-2 means, is that there is a connection issue at the moment between slot 1 and slot 2 and its trying to reconnect you, maybe bad ping you know, just wait a little bit wink.gif
there is one more option for you, tell the player with connection problem to rejoin, or remake the game yourself, also you could log out and log in again, and see if it works wink.gif
PS: A friend of mine can play only with me in online matches over gamespy, and with 90% of people there is no ping for him, but it works flawlessly for him over garena, hamachi, tunngle, game ranger etc. This is because of his internet connection, he said the provider cant open ports for him, so he needs to change the provider in order to play with everybody over gamespy
