Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello! I was having trouble using my password to create my token. I'm almost 100% sure that the password is correct. I have it written down and it works with the new elysium server(I can log in before being immediately disconnected). I had no problem getting my token via email, but could this indicate that there's something weird going on with my account? I'm technologically illiterate and scared.
