Just downloaded-Can't log in- Please advise

I followed Crix's new YT video on how to DL and logon: https://www.youtube.com/watch?v=EyEXR7JvIk0

I downloaded and moved to my Program Files(x86) folder. I moved the realmlist out to the front folder and changed it to set realmlist login.warmane.com

Upon launch, I don't see an indication of what server I am on.
When I try to log in using my Warmane credentials, as Crix said to do, as well as many others on this form...I get the 'Unable to connect. Please try again later.." error.
When I try to log on with my email credentials, I get past this screen and it starts to want to update/install a patch, when ultimately fails and i have to close the game.

What should I do?

Thanks

delete that client.

download the one provided here: https://www.warmane.com/download

Once the download is completed, do these 3 things:
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"

ok, giving it a shot. will get back to you. thx

remember to log in by using warmane account name (not email address)

Thank you! I am no in Q.

Crix's video is wrong
