"You may have a locked account"

If you try to log in unsuccessfully 5 times, your account will become locked. You will see an error message saying that "Your attempt to log in failed. You may have a locked account." (This is misleading. You definitely DO have a locked account, no maybe about it.)

Once an account becomes locked, you need someone to unlock it for you. Put in a support ticket for your account to be unlocked.

Tip: your account became locked because someone (probably you) entered the wrong password 5 times in a row. Consider changing your password after your account becomes unlocked.
