Just migrated my hard drive from a 2008 iMac 21" to a mid 2011 27" iMac and now InDesign 5.5 crashes when I open it (just InDesign no specific file) - have deactivated it from the 21" and reactivation on 27" was successful. It's part of Creative Suite Design Premiu, Photoshop and Illustrator are working fine, I've even trashed the Preferences and restarted but still the same error - PLEASE HELP!
Migration tool is never a recommended way for moving the applications from one computer to another , you should uninstall the InDesign and re-install it to make it work..
Will try a re-install and see if that works.
Re-installing worked thanks! Wish Apple would put out a simple 'What you need to reinstall and check after migrating' checklist!
