I checked your account in our database, and it doesn't look like it has been activated yet. This might be because you've just made the account, but be sure that you've gone to the link sent to the e-mail address you signed the account up with. Then, you should be able to log in within about 48 hours or so. If the link has expired or doesn't do anything after that amount of time, it's probable that you waited too long to activate the account and will have to try again with a new account.
Hopefully this helps. c:
