I used our old client.
Center@Mail.ru exe.
Then I got many error messages.
Then I decided to download english client My.Com GAMES.
http://en.allods.com/download
I changed the english client's language in settings from english to turkish,then client is restarted automatically. Then i canceled downloading of Allods Online EN, and i started downloading of Allods Online TR from selecting games +4 in client's tab.
This is my solution.
