Hey folks. I have a g4 superdrive iMac and went to install ilife 4 that I had bought off of ebay. When the install DVD spun and I clicked install, it told me that I had to close all applications (iphoto, idvd, imovie, itunes, garageband) before continuing. Here is my problem, none of them were open!. I restarted and shutdown, and I still got this message. I had to force quit idvd earlier in the evening if that has anything to do with it. Thanks in advance.
