I am in the middle of a job using CS 6, but at the same time opening the Creative Suite apps. I created an InDesign file in CS 6, saved it, and now I can't open it. I'm getting this message: Cannot open file because it was saved with a newer version of Adobe InDesign CC (10.1). You must use that version or later to open the file." AARRGGHH! So how do I access the file?
Sounds like you opened and saved it in CC, so now you need to go back to CC and either complete the project there, or export to IDML to take it back into CS6.
