I've downloaded every single client that's available on the downloads page. I've set my realmlist.wtf file to "set realmlist logon.warmane.com" for all the clients.
In WotlK, it wants to download the update, but the update is stuck on 0% and nothing else happens. I've tried it with both the normal and minimal clients. I've tried MoP as well, which doensn't have a realmlist.wtf file, which upon login seems to redirect to Blizzard's servers every time. I manually created a realmlist.wtf file for MoP, but it doesn't work.
I've yet to try Cataclysm but after the failures with both WotlK and MoP, I decided rather to ask for help here. Can someone please instruct me on what I'm doing wrong? I've also disabled the "Read-only" option from all the clients so it can't be that either.
