Nostalrius Begins - Quality wow vanilla realm (1.12)

Greetings,

I am new but i used the search and read the FAQ and couldnt find an answer. My game isn't working at all. I have installed twice using (viewtopic.php?f=6&t=638). When i go to start the game up, the game just goes black, i can sometimes hear sound but nothing after that, is my machine not configured to play this correctly?

specs are:
Intel Core I7-2600 @3.70
8gb RAM
64-bit operating system
Windows 7
NVIDIA GeForce GTX 560 Ti

I have two monitors that i am running at 1920 x 1080.

Any help would be greatly appreciated.

Thank you!
