Settings dissapear after closing the game

Hello there!
Im new to this server, im an old wow player and im coming back to play my fav expansion! :D
The thing is, when i open the game (3.3.5a WOD models, and i open the .exe) i log to my acc, everything is nice.. Buuuut, i change the game settings (Video to ultra and resolution to 1920x1080) and it says i need to restart for changes to be complete.
I close the game, reopen... and i have to accept the license agreements again, all ive changed is gone... it doesnt even remember my acc name... Hope someone can help me, i really dont want to go look for another server as this seems the perfect one.

Thanks in advance, hope for a quick response so i can get back to wow!
(Btw, gonna be a healer, heard those are sought for heheh)

Look at the thread below this one.

edit: i right click the folder... properties.. uncheck the read-only... apply > ok.. if i open properties again, its checked... after i uncheck it.. going mental with this

Try to close your torrent client.

i did... i also changed the folder to another directory

EDIT: SOLVED!! it was my antivirus.... please delete

I'm having the same problem, though I don't believe I have antivirus software running. Should I uninstall Malwarebytes?
