I'm having the same problem. The thing is I was able to package yesterday and everything was running perfectly until suddenly I coudln't package one of my files (as you describe). Today I can't package anything and I've already used and saved several projects using CC 2014 and I have to reopen and resave all of them as IDML in order to save the package of each one of them. This has been a real pain in my workflow.
