After last update 2X client can't login if windows server username is in russian, for example "Администратор". Login windows screen and error about wrong login or password are appearing. With latin credentials everything is Ok.
i am pretty sure i have seen this and read that they were going to fix it on the build that is about to come up..
Hm... I am really sorry, but i think i was mistaken. Now everything is working correctly. Maybe something was wrong with my server credentials.
