ok, let me be more specific
some files are getting damaged and when we try to open it in ID 2014 the ID crashes and get closed. Even ifthe file is openedon another computer. Some times we just get it back to a older version but, in some situations (for example, when we have to close the material and send to another company print urgently) it doesn't fits
i'll try to convert some the files to .idml and open in ID 2014 to see if it's works.
Thanks for your help
