Sounds like you managed to activate the anti-brute forcing password security feature.
If you get your password wrong 3 times in a row, it'll ban the IP for 10 minutes.
Since your account is a new one, it'll have made you have an email address on it.
I suggest waiting for the 10 minutes to be up, then resetting your password to something more memoerable via here:
