A client from another server

Hey guys i need some help, so i apparently have the ******* client but i want to play here and i think both servers are running the same MoP version ( 5.4.8 ) , but there is no realmlist.wtf file in this client i have atm. Can anyone explain to me how can i connect to Warmane's servers using this client ?

Thanks

We do not know how different this other client is. Your safest choice is to just download our client as if it was a different version.
