I just bought the game today and made an account. It said it only took 8 character to make a password, but that’s a pile of goat **** because it didn’t work. So in anger I typed in some not too polite words into the password thing and added like 12 number and signed up my account, I did write it down first though, tha’ts not the problem. Once I signed in it said there was an error, I turned off my firewall and think it’s fixed, but now every time I sign in it says I have the wrong password or username, which isn’t true, because I just signed into the forums fine. 
and I can’t change my password because I haven’t yet made a character, so….yea. thanks for any help.
