Can't chmod /etc/sudoers file

Hello,
I have installed linux mint 9.
I edited the /etc/sudoers file doing chmod 777 /etc/sudoers.
Now i can't do sudo chmod 0440 /etc/sudoers.

Code:

sudo: /etc/sudoers is mode 0777, should be 0440

sudo: no valid sudoers sources found, quitting

Code:

-rwxrwxrwx 1 root    root      641 2010-05-22 21:13 sudoers

drwxr-xr-x 2 root    root    4096 2010-04-27 16:43 sudoers.d

if onsoccesfol try to delete the file and then create a new one

It's fixed now.
I had to use recovery mode to chmod 0440 /etc/sudoers.
