I want to go back

any translation error is because of google(i don't speak fluent english yet)
My name is Eduardo(Edward), I am from Brazilian
I am old player of WOW, when I started playing I was still young and the serve was called MOLTEN. A few years later, I returned....but I lost my old account and I would love to get it back, I remember some account credentials, if recovery is possible

I created a new account a few years ago, but I always wanted to go back to the old one and today I went to log in to the new Icrewom server with this new account and I can't. this type of error appears{...support/Index.xml?gameld=11&rootCategoryld=2316}

I would like a lot of help from you in these two cases, if it is possible

If you didn't migrate your account when Moltdown happened you can't get anything back.

About the error, are you sure you are using account name and not e-mail?

I have the same problems with the same code, tried all kinds of stuff. Nothing fixed. Today in the morning i just got disconnected and from then i get either the error with 2316 code or it says: "Login Server Down".
