Nostalrius Begins - Quality wow vanilla realm (1.12)

I downloaded the Nostalrius wow client and installed the game but every time i start it it just plays the intro music but no picture and then it closes without no error or nothing. I tried reinstalling the game, running as administrator.
Anyone have any idea what is wrong and how to fix it?

Open config.wtf file and check the gxresolution. See if it has something weird like 1366x768/ Set it to match your monitor's resolution and save then try again.
