Video settings not saving

Hey all,

New to the Lordaeron server (and private servers in general). Everything is going smooth except that every time I log in, it plays the opening WotLK cinematic and doesnt save my video settings. All other settings seem to save just fine - character settings, macros, keybinds, etc. But I set it to widescreen and Ultra video settings, then if I close the game and come back later, it plays the cinematic again like I just freshly downloaded it, makes me re-accept the user terms, and my video settings are back to default.

follow these steps:
1) Restart your PC
2) close your Torrent client and move your WoW folder away from your Torrent's download destination
3) now right click on WoW folder> Properties> remove "read-only".
