you don't use 2 logins you set up a second shaiya server on another system with a different IP address.
when you look into gamegroup there should be Game01 you need to add Game02 and set the IP for the second shaiya server. as well as set the database IP for the new server. so the new server has it's own Gamedata, Chatlog and such and they both use the same Usersmaster DB
so both servers show up in the list when you log into the one ps_login.exe server.
Aeria has there login server on 1 IP and each seperate server has a seperate IP.
This is exlained
