WotLK Having trouble getting in the game

[SlugaSluga]

Everytime I log in it says I need to download an update but it doesnt move then tells me it cannot be completed. Ive followed guides on how to install the game properly and I believe ive done them all right but idk what keeps happening. Please if anyone has any info that can help it would be much appreciated.

Are you using a client download from here? https://www.warmane.com/download
