I've run a brief search but not turned anything up so far. Can anyone make any suggestions? Just upgraded from LA5.5 on OS10.2.6 to Pro 7.2 and OS10.4 - started with 10.4.6 from the OSX install disc then up to 10.4.8 in Software Update. Still no joy completing a full install of Logic Pro 7.2 - each time it gets most of the way through the Content DVD before saying there's an error in installation. Having said that I'm able to open 7.2 - haven't done much yet but seems OK superficially - but would like to hear any suggestions for completing the install properly.
