Not able to open existing documents in InDesign due to 'missing plug-ins'
I am no longer able to open documents I created a few months ago in InDesign. An error message flashes up to say that it is 'missing plug-ins'. However, I can still create new documents. I have tried uninstalling and reinstalling the software but the problem still persists.
I am a relatively new Mac/InDesign user so would appreciate it if you could talk me through step by step.
