Log-In Game Trouble

[ForgetAllTheProblems]

I know there is a lot of threads for this, but um... I'm still needing help on it. When I try to log-on in game it says wrong password or username when I try. I put everything in correctly, I tried all the passwords I changed it too and still, no result. I have no characters, because I just signed up for this new acc. I don't know what to do now, i'm getting frustrated.                                                                            Could Some Please Help Me? It'd Be Greatly Appreciated.

Is your username more than 16 characters long? If so, sorry but it won't let you log in and you'll have to wait for registration to open again. Or, if it includes symbols, it may be glitchy for you.

Oh, okay! Thanks. xD I'll just wait for another time and remember not to be it longer than 16 characters. >.<
