Why I cannot enter 1V1 arena?

Why I cannot enter 1V1 arena?

The system told me ：You or a player in your group uses a modified game client. to participate in battles in the Arena you need to download a clean game client and wait a while.

I once try to download client from your website.

But still cannot enter 1V1 arena. I once use chinese clean client.

Please tell me how to solve it.

Thank you very much.

Download this wow.exe https://drive.google.com/file/d/1I-J...lZLlEFEbU/view put in game folder.
Enter the game and wait until the anti-cheat check comes, be in the game for at least one hour.
