if i click on join icon from gmtrcker website it just opens cs1.6 but doesnt joins any server automatically as it was doing earlier .
it happened just while i was playing and tried to switch to diff server .

Are you already in-game when you are trying to do the "Join" button a second time? I don't believe GT can auto-join while the game is already open.

nopes ... its like everything is working fine and then i exit game to join other server from from gmtrkr website as i have done all the time .

but now it just opens cs1.6 game but doesnt join the server .

previously all that was needed was to click join and then it opened cs1.6 and connected to server simultaneously .

i just re-installed both gametracker lite and cs1.6 but problem persists .

when it worked perfectly it posted on my wall .. like xyz is playing on server abc
now it says ... e.g. xyz is playing cs1.6 .
plZ help

You could use CONNECT command. Type CONNECT command along with the IP address. e.g CONNECT 127.0.0.1:27015
You want to type this command in console by pressing ~ key.

Thanks!
