WoD model version problem

So, I'm using the WoD model version of MoP that the server provides, however for some reason my settings won't save and every time I launch the game I have to accept the agreements and to change the game system settings, is there any way I can make it save my settings?

goto the MoP directory, right click on the data folder, then click properties, a box will open, look to he bottom and you'll see attributes, read only. uncheck the box next to read only and click OK. Do the same for the WTF folder and then launch the game and it should save everything.

Thanks, it worked!
p.s. should be added as info to the download section.
