Technical Can't login

[Darknight80]

Hello

I have been trying to log in but when I try I just keep getting a disconnected from the server message, I have redownloaded the client I put it into a new folder, The realm list is set correctly, I also went and clicked on the folder and clicked properties then unchecked read only and then pressed ok but the problem is when I go back into properties the read only is checked again , I have tried this step many times and it just won't save, Anyone know what I can do please.

Thanks

I was able to login when I tried my username instead of using my e mail address and logged into straight away.
