I have an AppleScript app that I’ve been tinkering with for years and years, but which I haven’t modified for a while. When I tried to open it today in SD, I got the “cannot open file” message. The script runs, and main.scpt opens and saves in SD.
When I’ve had this error in the past, I simply copied main.scpt into a new AppleScript application, then copied all the Resources (lots of files and other scripts) from the uneditable one into the new one. But is there any way to repair the existing application so that I can continue to edit it, with recreating it?
