Nostalrius Begins - Quality wow vanilla realm (1.12)

I've tried creating an account, but I think the website may be bugged. Every time I enter my account information to register, on where my email information goes, there is an error message saying, "please match the requested format". There is no other information available to help me with this. Please someone help me. Thanks in advance.

Try to go on other PC (Computer) and make an account and then come back on your PC and your account will be created and fully working. And with that account you can log in to WoW Nostalrius Begins.
