I have CS 6. I opened a file with a trial version of CS7, In Design and saved the changes. The trial expired and when I tried to open it with ID 6, it said that the file was not compatible.
How do I retrieve an orginal file without having to buy the trial version? I have tried to download a new trial but I have been unsuccessul.
If you know someone used indesign cc send to him to save as IDML.
Or, you can give this a try. Install the script blindOpen_and_IDML-export that Willi Adelberger mentions here to convert the CS7 file to IDML and then try to open it in CS6:

That script won't work without a working install of InDesign CC.
