I also had the same problem. The quick fix for me was to attach a new net ( I called it "no_conn") to all the un-connected pins and re -generated the IPC file. I told the board house to ignore pins connected to this net. This seemed to work. I have a "IPC-D-356 for dummies" word document that I can forward to you if you like, maybe that will help.
