Hmm, so I opened Acquisition on my friends computer (G4 powerbook, 10.4.3, etc). It said that his OS was missing software, and I need to re-install the OS because it is a very serious problem. So, wtf is up? Could he have accidently deleted something? He goes to boarding school, home for the holidays. I'm his lifeline for his computer. I highly doubt he's got the orignal disks, any ideas? Would rather avoid going through downloading the torrents illegaly etc.
