Settings Never Save

I have a weird issue. It's not life changing. But every time I exit the game (wotlk). All of my video/interfacec/addns reset and I have to go through the whole process again about fine tuning them. I'm not sure what the issue is, but it never happened to me when I was playing in bc or mists. Just curious if I can fix the issue or if it's just something that comes with the territory?

Remove wow from torrent.

Stop torrenting, if u haven't already.
Then go to your wow folder and right click it. Open it's properties and there's "Read only" ticked. Tick it off.
