Solution Posted On Silkroadonline wont help,
C9 Error is something very special
when I first start game, it will tell C9 error,
after second restart it may also throw this error but usually logs on.
I have checked at both places, at ISP (I have friends there) and at home and there is NO NETWORK PROBLEM.
So the silkroadonline's solution is not an answer, nobody will block network traffic for the first time and allow for the next attempt.
