I have a major problem. I was using clean app to delete some old programs, and it deleted something to do with the system prefs. It just shows a question mark over the icon. What do I do??? Can i just install that program?
Just download and reinstall this. If that fails, I guess an Archive & Install would help. Back up your data although technically you shouldn't lose anything.
Thank you so much for your quick help. It turns out that there is not an archive and install option with the disks i had, but there is an option to upgrade and it worked like a charm.
