Can´t log in for the first time

Hello, i have donwloaded WotLk, then started it logged in and it said that a patch needed to be downloaded, so I pressed on download and immediately after that it logged me off with:Failed to apply patch. Please try again later. If this problem persists you may need to reinstall or contact technical support.

Please start the game from WoW exe and not the launcher. Also check your realmlist.wtf located in Data i believe. It should be something like this set realmlist logon.warmane.com

If it asks for patch download, use your username, not email! to login.
