Adobe InDesign is shutting down. A serious error was detected. Please restart InDesign to recover work in any unsaved InDesign documents.

This is my script

bb = app.books[0].bookContents;
for (i = 0; i < bb.length; i++)
chname= File(bb[i].fullName).name;
mynewfile = File(myFolder + "/" + chname);
if (mynewfile.exists) {
bb[i].replace (File (mynewfile));
$.writeln (mynewfile)
app.books[0].save();
Please advice me how to solve this prob?

Answer 1

You have a serious corruption problem someplace, or a serious conflict with some other software that is running.
If this happens with more than one document, you can start with repalcing your preferences. See Replace Your Preferences
If it's isolated to a single document, see Remove minor corruption by exporting
Another very likey cause is a corrupt or poorly made font. Run a font utility to look for font problems.
Turn off any third party Plugins for ID that you might have installed. Also try turning off your font manager if you have one.
If none of this helps, you may have to reinstall ID.
