InDesign CS3 has stopped working, saying it's missing the file /Library/Application Support/Adobe/Type Support/Unicode/Mappings/Adobe/Mac/ROMAN.TXT — but it's not. The file is there, right where it's supposed to be. What gives? I've relaunched, restarted, reinstalled; nothing's working. It's been running on an iMac under Snow Leopard 10.6.8.
