WotLK Login Server Down?

[Nekookie]

I downloaded Wotlk and when I tried to login it said "Login Server Down". I closed it and opened it again but it gives me the same error everytime. I tried searching for a solution but I can't find any. Is there a way to fix it? I have MoP and it works just fine, but Wotlk keeps giving me this error.

where did you get that Wotlk client?

Be sure you are using the correct realmlist: set realmlist logon.warmane.com

Edit:
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

I downloaded it from here and I tried the realmist fix but it keeps giving me the same error.
