Nostalrius Begins - Quality wow vanilla realm (1.12)

Yesterday my game began crashing very soon after I would log in and start questing. Sometimes it would last longer than other, but never failed to crash. Before yesterday I had zero problems playing on Nost. And now today I can't even enter the world, I instantly crash as soon as I spawn in. I even reinstalled a clean copy of the game from the Nost guide today and still I crash instantly as I join. I'm not sure what to do! Below is a link of a gyazo of the crash. I do not have much knowledge of the game files/crashes so maybe there is an easy fix I am missing but if anyone could help that would be great.

Do you have a nvidia video card? update the drivers.

and....Go into your System settings, on the left column click on Advanced. Once in this new tab, look for "Graphics API" and set it to DirectX 9

Make sure you are operating as administrator in WoW:
