Currently I'm running 10.3.9 (waiting for Leopard) and iLife. (2004) Just today, iMovie won't open at all, either from the task bar or the applications folder. I'm thinking about putting the software discs that came with the G4 into the machine and trying to restore iMovie but am worried I might re-initialize lots of things and lose setting or files. I don't want to lose any data files that iMovie has in the Movies folder. Can anyone help ?
