SOLVED EDIT: For those having similar issues, I changed the root folder name and moved it to the C:/ drive.
It now sits at C:/Nostalrius and works fine!

I downloaded the client from a torrent since the mega was down (VanillaGaming_1121_Pack.rar).
I've created an account and copied the new realmlist in and get the "The information you have entered is invaid" error. I have tried changing the realmist to just say "realmlist login.nostalrius.org" with an empty line below it and it doesn't work.
Is it my client or do I need to tweak the realmlist?
I don't know how to take a screenshot within the WoW client, but it is Version 1.12.1 (5875) release. Error is "The information you have entered is not valid. Please check the spelling of your account name and password. If you need help in retrieving a lost or stolen password and account, see
