    Indesign CS4 files won't open in CS6


      Installed CS6 on new MBP. Moved CS4 design files over to new computer.


      Files won't open in CS6. Get the following message:

      Cannot open "filename.indd". The file "filename.indd" is damaged (Error code: 4).


      This happens with ALL of my CS4 Indesign files. (*Note: they DO open on old MBP)

      I tried exporting one as IDML on old machine - same thing.


      Any suggestions? I was told all older version files will open in NEW CS versions. True?
