WoW Disconenct on Windows 10

Hi!

I recently installed Windows 10 x64 on my computer, and there is a problem with Warmane WoW.
Anytime I connect to server, I get the message: "You have been disconnected from the server". Even if I am on the character select page, even in game.
I tried 1 other server with the same client, and it worked. So the problem is with the server.

Please help me, if you can! :)

Update1: I get the error exactly 1 minute after logging in.

Maybe u should wait until 29 Juli for the official update, instead of installing Betas or cracked szene releases?

Ye, i know that this is not the final release, but on other servers, this client worked fine. Thats why I write here.
