Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello, I successfully installed the game and created an account, but when I try and log in, it tells me the account doesn't exist (I did create the account correctly). However, when I try and look for solutions, I see that my "Data" folder is only meant to contain 2 folders "Patch.MPQ" and "Patch-2.MPQ". However, mine does not contain either of those but it contains this : http://gyazo.com/ba6b0148ee464e6511f64ef64fc18292.

Any help would be greatly appreciated, I really want to experience the nostaliga.

Cheers.

Greetings.

Follow the tutorial in the link below, and try to download it once again (It might help to try and reinstall the client)
