Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi. I just installed a fresh copy of the game (from the tutorial in the forums). When I try to launch it, I receive the following fatal error message. What's the problem, and how can I resolve it? Thank you so much!

Greetings,
you can try few things, but my opinion is that your problem is related to dx11. try to switch back to dx9 and see if the error still exists. I had a similar problem on retail version last year.
I hope it helps.
