Its the Player_Kick_Message_Ack packet kicking you out.
I used to reverse the error codes' constants/strings from the packet :
Code:
-B01 Client not responding
-B02 Query timeout
-B03 Game restart required
-B04 Bad service version
-B05 Disallowed Program
-B06 indicate cheating
-B07 corrupted memory
-B08 corrupted data
-B09 WinAPI Failure
Global ban
-B10 Bad packet
