just bought a new MBP and final cut studio 2 started to install then half way through the install of audio contact disk one, it asked for the install disk again, but didnt eject the current disk. I manually ejected it and put the install disk back in. the computer then said the media was damaged . .... i was using the internet at the time and downloading messenger for mac. do you think this might have caused the error or is there a problem with my programme, ive been very careful with the disks and literally was opening the envelopes as it asked for the disks , advice anyone ...?
