Nostalrius Begins - Quality wow vanilla realm (1.12)

I have tried a whole lot of times to get into the game. It was working for a little today. It takes me to the log in details, i put them in.. Last thing i get is Success! Then nothing.. If i say cancel it says retrieving realm list but that also just sits there. I have tried a whole bunch of fixes. Checked my net speed and everything else. Even asked someone else to log into my account from another pc. And it worked. Does anyone have any suggestions?
thanks awesome people

If you're getting to "Success!" and it's just hanging there, or if you click Cancel and it sits at "Retrieving Realm List," that means you're able to login to the login server successfully (Legitimate account name and password) but your computer's having trouble connecting to the realm server (The last part before you see your character list).

How long have you tried letting it sit at "Success!" or "Retrieving Realm List?" Some people have reported that during peak hours, it can take several minutes before they're able to get past these screens.

Thanks I'll try that. Seem only to happen in afternoons and evenings.
