Return of Reckoning

Everytime i go to log in through launcher i get wrong password i have changed my password tried again same problem any ideas?

Also wanna add "This happens when you use numbers or special letters like russian letters or for example: á à â. Change your password (8 digit seems to be fine. It may take some days before working with login server) or create a new account." is not the problem here

I have the same problem. My password doesnt include any special characters, not even numbers or capital letters and it is 8 letters long. Waited a few days, but I still get the same message in launcher: invalid username or password. Any help would be much appreciated!
Thanks in advance.
