Nostalrius Begins - Quality wow vanilla realm (1.12)

I was playing when the server crashed yesterday and was disconnected. Since then I haven't been able to log in to my account, when logging in it will get to connected then immediately 'Disconnected from Server' every time I try.

I am able to log in to a different account and my friend can't log into my account from his pc either.

Has anyone else experienced this problem or have any idea how to fix?

Thanks

I have the exact same problem. I made a new account aswell and I can connect to that one. I dunno what to do.
