Looks like both drawings have a layer state with the same name "ACAD_VIEWS_Vue1", must have been created by the acad vertical product that was used to create the drawing you are inserting and the drawing you created. The odds that both drawings would have the same layerstate name had they been created by different user seems pretty slim. I would try renaming the layerstate in the drawing you are trying to insert to something else then try re-inserting.
