Okay, great. Your file system should be fine now...
Enter these terminal commands to create a brand new admin account (hitting return after each line):
mount -uw /
shutdown -h now
4. Once the Mac restarts, you will be given the choice to create a brand new user.
5. Once the user has been created, you may use it to modify the password XXXXX your original account by going into System Preferences > Accounts.
6. Then, log out of the "new" account and back into your original user account.
7. Once back in your original user account, you can return to System Preferences > Accounts and delete the "new" account you made.
