I have a singular document in indesign cs6 that doesn't open in indesign cc.
but it crashes whenever i try to export it to idml in cs6. another idea?
I've moved this to a new thread of its own and changed the title...
It sounds like the file is corrupt. There was a script floating around not long ago that is supposed to export to .idml without opening the file. You might want to see if it comes up in a search. There's also a tool for Windows that might work: Adobe Community: Program for restoring corrupted InDesign documents (for Windows only) I've had little success with it, but you never know.
There's also the markzware recovery service if you really need the file and rebuilding would cost more than a couple of hundred dollars.
