I was having exporting to pdf issues in In Design cs5, after a lot of troubleshooting (all unsuccessful at pinpointing the issue) I checked for recent updates and downloaded the adobe updates available. Now I can not even open Indesign, it crashes immediately. Any solutions that do not involve uninstalling and reinstalling the software would be greatly appreciated. This is my desktop at work, and whoever installed the software before I started here did not record the serial number and so I can not reinstall/uninstall or upgrade. Help!
