Compability problems between different versions - LOCKED
Our designer (located in Poland) is using the Creative Suite 5.5, we (located in Germany) are using an actual Cloud version of InDesign. The problem is, that we cannot open files designed by our designer, make modifications and send them back to him. That makes it very difficult to create a catalogue e. g. where we are doing the text and our designer the design and final arrangement.
What can we do to solve this problem?
