Lost preferences, bookmarks, screensavers, etc on Admin user.

Question

Hello,
My husband accidentally lost all of our preferences on our computer, bookmarks on Safari, screensaver folders, etc. We are under the Admin user is but cannot figure out what has happened or how we lost everything. We have logged in/out and shut down, reinstalled Snow Leopard. It started when he was on Safari and locked up, then don't know what "discussion" him and the computer had but apparently the MAC won!!! Can someone please tell me how to fix it?
Thanks

If you have only one Admin account on the machine, your going to have to so this trick to create another, in doing so the Library folder of this new user will be created and you'll have control of the computer again.
Hold the command and s keys and reboot the computer, a scary black screen appears with a lot of white text runs down the screen, wait until it's finished and backspace to clear any extra ssssss....
Type the following commands at the command prompt, and then press Enter after each one:
Don't make a mistake
mount -uw /
rm /var/db/.applesetupdone
reboot
mount *space* -uw *space* /   then press enter
rm *space* /var/db *space* .applesetupdone  then press enter
reboot then press enter
The Mac OS X Setup Assistant screen should appear after the reboot, just as it does when you start up a brand new computer or upgrade to a new version of Mac OS X.
Create a new user account with the Setup Assistant. Be sure to name this user something different than the admin user that already exists on the system.
At the end of the Setup Assistant process, the system will automatically log into this new user account.
