I think my account has been compromised.

I can login my account. After I login, I can still see my user name and my balance on the top right corner, but it said "Not logged in".

Can someone confirm me if my account is hacked??

Am I screwed???

Update: I try to use forgot password function. I entered email, but it didn't work, so I think they changed my email.
So I submit my username to reset my password (even I know I won't receive the email).
But a few minutes later, I receive an reset password email in my original email account!
WTF is happening with Mt Gox???

Another update:
After I reset my password to 24 character, I am able to login and my fund is still there.
But I am very skeptical about using Mt Gox now.
