Got a problem

[Asia]

So, I heard servers are back on and i'm happy!

But when I attempt to log in, It shows me error login failed, it's been doing this sense day 1 the servers were knocked out, and what's funny, is that i know my password! 

anyone has tips? 

Well, judging by the image you attached, you are putting your username in wrong. But if that's not the solution, try deleting and reinstalling the game.
