An error message just comes up "an unknown error has occured". Does this mean that I can't open and edit all my old stuff???? Please tell me there is something I can do. I have upgraded to a MacBook Pro running 10.5.7 and CS4 from a PowerBook running 10.4.11 on CS.

Never mind - I just closed Illustrator and tried again, and it worked. I have had it open for a couple of weeks working on a project, so it must have just needed a rest. Phew!
