WoD models, cant remove them!

I downlaoded the wrong one and didnt want the WoD models, I read how to get rid of them by deleting the two files people said, i made sure they were the right ones, the ones with the W in them. patch W and enus W on, how do i get rid the models if removing these two things didn’t work?

Anyone? some npcs are just tiny blue adn checkered boxes because of the WoD models.

I don't use the WoD models so I'm not much help, but you could always just download the old client from the download section.
