(I cant log in, every time I try to login, message pop up at me. It says: Update 0%. I was waiting for long time and after that, it just crash to the main menu. Game said, that I havent any patch. I dont know what to do...) - I solve that problem already I think, but I have another problem, I cant rerwite my Realmlist.wtf. What to do?

Tutorial on how to update your realmlist to Warmane.

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

Or you could make a notepad and write there the following line:
set realmlist logon.warmane.com

Save it as Realmlist.WTF and move it to your Data/enUS* folder |* or whatever language pack you have.
And overwrite the old one with the new one.
