Inside NeuzMsgProc.cpp look for this bit of code
Code:
g_Neuz.m_bEncryptPWD = TRUE;
Underneath that there should be this bit of code
Code:
if( strcmpi( szArg1, "
what ever is inside the "" remove it and try again!!!!
If it still doesn't work post here and i will try TV you to help :)
also if you have ran a server for years (i assume without the source you should know you have to res hack the neuz msg_ver and port (i can help you make these 100% inside the source so if someone tries to edit the msg_ver and port it will be used as a decoy only) )
