I'm trying to open both an inx file as well as an idml file exported from CS5. I have CS4 and it is updated as far as it will go, but it still says I'm missing plugins. And a lot too... 19 of them! Does anyone know how I can get these plugins? It's requesting them for both the inx file and the idml file.
That is indicative of someone simply renaming an INDD file to IDML. In other words, that file wasn’t EXPORTED from anything. It was saved with a different extension or renamed after saving.
