Wotlk client

I downloaded the client for wotlk on the warmane site, every time I shut down the game all my settings and xperl reset to lowest setting. I have to reconfigure every time I login and it’s getting very annoying. Anyone else had this issue? Anyone know what I could do to fix this?

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".

Thank you very much, it worked!
