I can't log into online servers, because there's still this error coming out. I tried everything, even changing my nickname, but it didn't work. The only hint that game gives to me is to look into net.log file and if I open it, it says that during logging there's this error that says that my nick is valid. What should I do to log in? And it only doesn't work when I play on my old account. Everything is good when I create the new one
