I know this is an old post but it may help someone, who knows! I have been encountering the same problem at our office except using mixed versions of autocad (2013 and 2011). A work around to this message / issue is bringing in an object into our drawing by insterting a block/object rather than copy/paste, or drag/drop an object.
If you're in the design library trying to drag/drop an object when this message appears, than simply right click the object and choose "INSERT."
Try this...I hope it helps.
