Nostalrius Begins - Quality wow vanilla realm (1.12)

So I put in my user name and password and it goes to "Connecting" and then goes to "Disconnected from Server" afterward. I am currently unable to log in in any way. I uninstalled and re-installed and haven't made any other changes to my computer. I was able to log on Saturday but haven't been able to since.

Any advice?

Hey hulksmash,

You may be connecting to a test realm. You'll see the realm name at the bottom right of the login screen. If this is true than log in and hit the Enter key quickly as soon as you see Success then change the Realm to Nostalrius Begins.

Thanks Snow240 but I'm set up for Nostalrius Begins so that's not the issue. It's not even getting to "Success". It basically taps out at "Connecting" directly to "Disconnected from Server".
