Disconnected upon logging in

I just installed the wow client and had an issue with my account info being incorrect. i fixed that by changing the realmlist.wtf
However, when i run the wow.exe from the extracted folder, and enter my log in information, i receive a "Disconnected" message every time i try to log in.
Anyone know a solution to this? have tried deleting WTF and WDB folders, also, i have not seen a realm selection screen yet.
