Suddenly after upgrading to 10.5.2 and when trying to start Illustrator CS3 only a sad information bulletin says that "you cannot open the application because "Adobe Illustrator" is not supported in this architecture". Before the update there was no problems what so ever. And yes this paid version not warez. What can I do? With no TM backups done in 5 months is the only solution to reinstall the entire machine?
