Can't log in into the game: weird critical error.

Hello!
Could anyone help me please?
When I try to log in into game it crashes with this error:

I have never experienced such error, and my friends failed to help me.
I deleted Cache file, but it didn't work.
I don't have WoD-like models.

What else could I do?

try to download the client again

thank you, I will try that.

let me know how this turns out because my client was working fine now in outlands gives me an error loading felorcmale and female models and wont let me in at all. DIdnt do that the first time I leveled a character up. Also have in the past redownloaded the client from each of the mirrors and torrents. Not using the newer cata models either.
