I recently saved a file in InDesign CC and then upon returning from vacation (NO changes to machine/software), received an error message stating that the file was saved in a newer version! 10.0 to be exact. Installed version is 9.2.2 x64
Sounds like you might have both CC (version 9) and CC 2014 (version 10) installed and you opened the wrong one.
Thanks Peter. Don’t ask me how --- but you were right!
