I downloaded the WotLK (old) plus windows client. It downloaded fully and I open it up using Wow.exe. I know i am supposed to use my user and password but when i use my username, it says cannot connect to server. I attempted to use the emaill i used on warmane, it lets me in and sends me to a page that says 0% patching, then it just disconnects me off without downloading any patch. I keep trying to use my username but it wont let me in. I checked the realmlist file and it shows the correct server location for warmane.
Follow these steps:
1) Restart your PC
2) close your Torrent client and move your WoW folder away from your Torrent's download destination
3) now right click on WoW folder> Properties> remove "read-only"
