Copy the crash report to Pastebin.com and then post the link to that here.
I am having the same problem. My editor used inCopy and I have upgraded to inDesign CS.
For the past few days I have been able to send her assignments and she has edited them and sent them back-- and I am able to open them and update the content in my inDesign files.
But yesterday the returned assignments all started crashing inDesign.
It would be great to find out what the problem is.
I got another crash. This time just on trying to launch inDesign.
Below is the report. If anyone can help it would be very appreciated.

I'm having the same problem too. Editors making changes in InCopy CS6 and saving fine. They can reopen the file and all their changes are still there. When I open the file in InDesign CS6 and allow it to update the assignments, it crashes. If I don't let it update, but then manually re-place the text from the ICML files, it works, so neither file seems to be corrupt. These are all new installations on new iMacs.
Any help much appreciated!
Again...PLEASE do not post crash reports here.
I am having a similar issue. From InDesign CS6, when I try to update assignments, InDesign crashes. I am able to check in/out the InCopy file fine, just the update the content function does not seem to work. I do not receive any other error message except the Adobe InDesign CS6 has stopped working.
I don't want to have to Unlink the Connection, recreate a new InCopy file and relink to InDesign. Is there a solution to update content in Design?
Any help is appreciated.
