Hello I seen on the log in page to change my realm list to 127.0.0.1 I did so and it also tells me to change it in the DB I i see in the core folder db and i've tryed to open it but it fales when i do. what am i doing wrong? also at the top where you posted you say to Copy the WoW.exe and paste it where your world of warcraft Cataclysm version 4.0.6 build 13623 is installed. do you mean copy the core where the wow.exe is or copy the wow.exe to where the core is? and thanks for the help.
