Ever since upgrading, InDesign won't even open. Crashes upon startup. "Sends to apple automatically" but what ever really comes of that? Anyway, I don't have the original install discs anymore (lost in the move between offices) so I can't reinstall. But my work depends on this!
I tried deleting the preference file. Same thing happens.

If you did an inplace upgrade, uninstall ID and reinstall.
I don't have the original install discs anymore
