Every time i log in,i have to remake all my setting, inculuding resolution and stuff. Also, i have to agree on the blizzard stuff and the rest. It's like it resets every time i log out of game, like it's my first time logging in. If anyone has a solution, it would be more than welcome.
I know you posted this a long time ago but a solution was posted in the bug tracker and I wanted to share it with you. Apparently all you have to do is go find your wow directory, usually C:/wow35 on windows, and right click it, go to properties, uncheck the read only box, and apply. I was having the same problem and now I don't. Good luck!
