I'm not sure about this one... I would check your opcodes.conf file maybe?
This is what mine says and it works:
Code:
#EQEmu Public Login Server OPCodes
OP_SessionReady=0x0001
OP_Login=0x0002
OP_ServerListRequest=0x0004
OP_PlayEverquestRequest=0x000d
OP_PlayEverquestResponse=0x0021
OP_ChatMessage=0x0016
OP_LoginAccepted=0x0017
OP_ServerListResponse=0x0018
OP_Poll=0x0029
OP_EnterChat=0x000f
OP_PollResponse=0x0011
But we're getting into territory where i may not be of much help :P
