I am getting an error message that I need to upgrade plugins to open a file that was sent to me. It is an InDesign document and the error message lists about 5 things all ending in .rpln
I've completed all of the updates on my InDesign software...what else can I do to make this file open? I'm quite new to InDesign, so I apologize if this is more simple than I am making it to be...
Thank you for your help.
Someone sent you a CS5.5 file. They are not backward compatible.
As them to export the file to .idml and you should be able to open that.
