    InDesign Document won't open.

    McHugh David

      Hi Guys.


      I have the most recent up to date CC. I opened and worked on an InDesign document that was CS4. I saved it as an 'idml' which can be opened down to CS4.

      No problem. However, when I went to open this document in CC I got this message:


      Cannot open the file "Cleggs.idml". Adobe InDesign may not support the file format, a plug-in that supports the file format may be missing, or the file may be open in another application.


      Well, it wasn't open in another application, as I explained above, it's saved correctly for what I need it for. Which leaves plug-ins. I haven't had this problem before, it was working fine last night. If it is the plug-in, how do I know? and how do I get the plug-in?


      Thanks for any help you can give!
