Downloaded Wotlk Client, Automatically wants to download to 4.0 when I log in

Hello,

My friend has recently downloaded the Wotlk client and it automatically wants to download to the 4.0 client when he logs in. He's using the wow.exe and not the wow.launcher. We've tried deleting the cache folder, installing and uninstalling multiple times but it keeps wanting to update to the 4.0 client. We used the link provided by warmane to download the server. Any thought or suggestions? All is appreciated.

Thanks.

Use your warmane account info. Not your email.

I've also deleted my launcher and patcher. They do nothing for you when you're playing on a prserver.
