Don't jump to conclusions too quickly, Arabis - first double-check to make sure both your login name and password are correct.
It does look like you were recently referred as a compromise through our webform, but that does look like it was from you, so a password reset likely has gone through at this point. Check your e-mail for that information, and double-check your spam folder to make sure that e-mail made it to you. I don't suspect a compromise in this situation from what I am currently able to see, but if you still feel you may be at risk, then take a look at our security tips and account compromise walk-throughs I've listed below.
