WotLK WOTLK Login Issues

[GoldLink]

I tried logging in but for some reason it tells me "Unable to connect. Please try again later." Im logging in with my account name not email.
Any one know the reasoning behind this or what I can do to fix it?

be sure you are using the correct realmlist:
Wrath of the Lich King
1) Go to your World of Warcraft folder
2) Double click on your "Data" folder
3) Double click on your enUS (or whichever language pack you're using) folder
4) Right click on the file named "realmlist.wtf", open it with Notepad.
5) Replace ALL of the text in this file with the following: set realmlist logon.warmane.com
