At what point does it crash? During startup or while working on a file? Any file, or one particular file?
Version of ID? OS? Error messages?
It crashes while working on a file. I also noticed that it only started crashing after I opened one particular file. I decided to try opening another document later and it worked. But when I tried to open that same file that made it crash, it went back to crashing anytime I opened any file. I wonder if I need to uninstall and reinstall. There are no error messages other than the option to submit a crash report. I'm working in InDesign CS5 with a Mac OS X 10.8.5 operating system.
Start by exporting the problem file to IDML. See Remove minor corruption by exporting
If it crashes while you try to do that, try the script at Adobe Community: InDesign 6 is crashing when attempting to open a particular document. All others are opening OK.
