I'm rather sure wolffox already mentioned this, but to solve this
Make sure you aren't using the numbers on the numpad, just use the numbers above the letters.
The password is capital sensitive, so if you write a small "s" when it should be "S" it will see it as wrong password.
Some of the symbols might not work either so best would be staying away from them in both username and pw.
If you already tried getting it to work by doing the things above, you simply need to create a new account.
Try to use just letters a-z in both the username and the password, skipping symbols, numbers and capitals.
