I have changed passwords because I thought I was being hacked(I was playing earlier this morning left then tried to log back in) the account names and passwords are correct. and both accounts show as active.
are you able to log into your account at the web site? I am not asking about the forums gut the actual game website.
If so then you are correct that your PW is right. The next question would be what is happening when you try to log in to the game? Devil is in the details.
