Client Issue

Hello, yesterday I downloaded the client and I'm experiencing a major issue(for me that is). Every time I start the client, my video/sound settings are set to default and I have to adjust them over and over again. Wondering if anyone has experienced this or knows how to fix it. Thank you in advance.

Follow these steps:
1) Restart your PC ( this is important)
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".

It worked, thanks!
