OS X LION 10.7.3 System Preferences

[PABSOUL]

Hello everybody, I am new in the Forum. Forgive my English, but is my second language. I hope I am posting this thread in the right place, If not, please forgive me. I am having problem loading some System Preferences Apps. They are actually three, "Desktop & Screen Saver", "Spotlight" and "Energy Saver". I tried fixing permissions, reinstalling system preferences using an app called Pacifist. I tried reinstalling OS X Lion, but everything seems to fail. The only thing that didn't fail was a clean reinstall of the OS, but I don' want to have to reinstall everything again. I have everything backed up in Time Machine, So when I reinstalled the OS I transferred all my DOCS and Apps from time machine. I am not good with terminal but if someone could guide me in right direction to fix this I will appreciate it.
Here is a log from console with the errors and what I think it seems to be wrong. Please help me out to fix this. Thank you

Most of the time this kind of problem is caused by a corruption in the System Preferences property list. You can simply delete their .plist file to reset it. When the OS will detect the .plist file is gone, it will reinstall the original (uncorrupted) .plist.

Go to ~/Library/Preferences/ and delete the com.apple.systempreferences.plist file.

~ is your username, make sure your Library folder is visible as it is hidden by default in Lion.

If your Library folder is hidden, you can use the following code in Terminal to make in visible:

chflags nohidden /Users/[username]/Library/

Just replace [username] with your actual username before pressing enter.

Alternatively, you can simply delete the file directly with the Terminal without making the Library folder visible by typing:

cd ~/Library/Preferences/
sudo rm --f com.apple.systempreferences.plist

You will have to type your account password (even though it's not showing) and press enter.

Chances are that this will do the trick.

Thank you very much for your time and patience to explain me what to do. I followed your instructions and deleted the com.apple.systempreferences.plist
but still not working.
I want to upload some screen shots but I don't know how to do that. There must be something else wrong because I can't even open Mail, I just realized that too. So I don't know what to do from here.

I'm having the same exact problem with Mail, Energy Saver, etc. A solution?
