Getting continual efile error, and I've tried everything. Can someone explain what this means?

ATEExceptionMessage: Processing efile payload request for efileId in.ny.nyc.1127 and instance tag[None] failed. Unable to find any applicable document set in the ooEFXML output order.  (It then lists a bunch of document sets found and checked.) 

If this were in English, maybe I could find the error...anybody have an answer?
