    Error - Cannot add data to "unknown document"


      I have had this happen to me twice in two days.

      The file which I save constantly as I'm working on, comes up with this error and I can't open the .indd file. 

      I don't have any network, new external drive or installed any new updates that might affect things.

      What's happening?? 

      I appreciate any help, and I am not too computer savvy...
