Hello, I upgraded to mac os x.4.3. I have an ibook g3. Anyhow, I'm missing a few of my applications now (iphoto and appleworks among them). I tried using the original software restore disks that I have. However, at a certain point it tells me to insert disk 1 of 3, which is already inserted, and nothing else happens. It only gives me the option of quitting. Can anybody give me a hand? Thanks in advance.
