It's either CS6, or it's CC 2014, but that really doesn't matter in this case, I think.
Depending on your OS, see either INDDRecovery — a program for restoring corrupted InDesign documents on Windows or Repair corrupt InDesign Adobe files on Mac OS X
I downloaded the Stellar Phoenix InDesign Repair, but when I try to upload my document, it says the selected file version is not supported.
What can I do?

You can try the script at Adobe Community: InDesign 6 is crashing when attempting to open a particular document. All others are opening OK. or use a paid recovery service if the cost of starting over is high. I've seen one report of Adobe fixing a damaged file, but I have no idea who to contact for that, and they are about to go in holiday break until January.http://forums.adobe.com/message/5073406#5073406
