cant save my options!

Hey guys! Every time i quit from wotlk my saved options are disapearing. I mean all the options for graphics, client and etc. Everytime it's oppening, starting with cinematic and even though i thicked the option, which remember me, there is nothing inside. I fully downloaded it from this site. Btw i dont use any virus program. Long before i played in pandaria and with that client everything was ok. What should i do? Anyway thank you!

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".

Yes it works perfectly now! Thanks a lot!
