I just remembered why it crashes your server. The lines that crashes the server are:

pawn Код:

SendClientMessageToAll(COLOR_USA, "[Army]: Player %s has joined Army Team !");
// AND:
SendClientMessageToAll(COLOR_RED, "[Terrorist]: Player %s has joined Terrorist Team !");

Using %s in SendClientMessage/SendClientMessageToAll functions will result in a crash. However the solution has been mentioned already 3 times in the above posts.
