WotLK Game client not saving my effects and video settings

[ThisBirbInocent]

Basically as the title says, every time I launch the game it launches with the default windowed mode with low graphic settings. I can change it every time, which will fix the issue if resolution is changed when effects are changed, otherwise it requires a restart and the issue just repeats itself. Even still, the issue repeats itself the next time I launch the game and I have not been able to figure out why >_>

Edit: Nevermind, the folder was set to read only somehow.
