The Enigma Order

Maybe someone could help me here...

Everytime I start WoW the multisampling settings reset to 1x, while I want to use the max 8x. If I set it to 8x, exit the game and restart it, it is reset to 1x.

Does anyone know how to save these multisampling settings? It's kinda annoying to change it manually everytime I start WoW and I guess it's a simple fix somewhere. Oh and google only gave me some dead-ends sadely.

Is it possible that it has something to do with administrator rights or something? Can I change something in the WTF folder config file to make it work perhaps? Is it related to another graphical setting in the video settings?

Thanks in advance!
