I've downloaded Pref Setter, but I don't know how to use it. For example users & group accounts, desktop & screen saver or disc utility are gone in system preferences but I couldn't find them anywhere on my MacBook 10.5.8. And also the default system preferences are also gone. Whenever I tried to launch it, it says the application quit unexpectedly and I couldn't find it in the trash bin. I think I have deleted them using secure empty trash. Please help me. Thanks!
