Dear scripters

here I am trying to relink the book contents from different path. While I am running this script my indesign cs2 is shutting down.

the error is below

---------------------------
Adobe InDesign

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

var myFolder = Folder.selectDialog("Please select a folder");

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?

thanks in advance
